GTA5 JetPack Mod [.NET] version 1.1 usually fails for one of five practical reasons: its two files are in the wrong GTA V installation, a required .NET dependency is missing, the game edition or build does not match the tools, Script Hook V is incompatible after an update, or the menu key was changed. Work through the checks below in that order before reinstalling everything.
The mod listing was last updated on June 3, 2020 and names GTA V version 1.42 as its minimum because older builds do not contain the jetpack model. That historical requirement is not evidence that the mod works on current Legacy or Enhanced builds, so treat present-day compatibility as an open question rather than a promise.

Which jetpack mod is this guide about?
This guide covers GTA5 JetPack Mod [.NET] by Mrtank, version 1.1. The listing describes configurable friendly and enemy NPCs and says its menu opens with F5 by default. The key files are GTA5JetPack.dll and JetPackSettings.ini.
Those details matter because similarly named jetpack scripts can use different loaders, folders and hotkeys. If your download is not this .NET mod, use its own installation notes rather than copying this file layout blindly.

What should I check before changing files?
Back up your saves and the GTA V installation before removing or replacing loose files. A general single-player mod installation guide recommends a backup because updates and troubleshooting often involve files in the game root. An external drive can hold a copy, but no particular storage model or capacity is required.
- Close GTA V, the Rockstar launcher and any mod manager.
- Make a copy of your save files and the current game folder, or at least the root files you plan to replace.
- Write down your game edition (Legacy or Enhanced), installed build and the date of the last update.
- Keep the downloaded mod archive unchanged until the installation is confirmed; this gives you a clean source for the two mod files.
Do not test the script in GTA Online. The official Script Hook V page says the library is for custom *.asi plugins and that it closes GTA V when the player enters multiplayer. The installation guide likewise warns against loading single-player mods online.

Where exactly do the jetpack files belong?
For this .NET script, both files belong in the active installation’s GTA V/scripts/ directory:
GTA V/
├── GTA5.exe
└── scripts/
├── GTA5JetPack.dll
└── JetPackSettings.iniDo not put the DLL beside GTA5.exe, in a downloads folder, or in a different copy of GTA V. A .NET DLL is loaded by ScriptHookVDotNet from scripts. By contrast, an .asi plugin and its loader files normally go in the game root beside GTA5.exe; moving an ASI into scripts does not turn it into a .NET script.
Open the folder from the launcher or shortcut you actually use, then verify the full path. Multiple Legacy and Enhanced installations, old backups and modded copies make it easy to place the files in an inactive directory.
Which dependencies does GTA5 JetPack Mod [.NET] require?
The mod listing names four dependency groups:
- Script Hook V compatible with your installed GTA V build.
- ScriptHookVDotNet (SHVDN).
- NativeUI.
- A mod that unblocks spawning GTA Online vehicles in single-player, as specified by the listing.
Install each dependency according to its own current instructions and the edition you run. “Latest” is not automatically the right answer: a new game build can require a matching Script Hook V release, while an older .NET script may not have been updated for newer SHVDN changes. The sources do not establish that JetPack Mod 1.1 supports current Legacy or Enhanced releases.

Keep loaders and scripts from the same toolchain where possible. If you have several copies of ScriptHookVDotNet, NativeUI or loader files, remove duplicates only after making a backup; duplicate versions can make diagnosis harder.
How do I confirm that my game edition and build are supported?
First identify whether you are running GTA V Legacy or Enhanced. Their mod files and tool builds are not interchangeable. Use the edition-specific instructions for Script Hook V and ScriptHookVDotNet, and do not copy a root loader from one edition into the other.
The jetpack listing states version 1.42 or later as its minimum because versions 1.41 and earlier lack the jetpack model. That is a requirement from 2020, not a current compatibility guarantee. At the time of this research, the official Script Hook V page listed a release dated July 15, 2026 supporting patches 1.0.3889.0 / 1.0.1158.13. Compare those values with your installed build on the official page rather than assuming that any newer or older file will work.
If Rockstar updates the game and Script Hook V has not published a compatible release, the jetpack script can stop loading or the game can crash before the main menu. Waiting for a compatible tool release may be the only safe option; repeatedly replacing the jetpack DLL cannot repair a loader mismatch.
Why does the jetpack script do nothing?
A script that produces no menu, NPC or jetpack effect is usually not being discovered, is missing a dependency, or is responding to a different key. Check these causes in sequence.
- Verify the path. Confirm that
GTA5JetPack.dllandJetPackSettings.iniare in thescriptsfolder under the executable you launch. Check the spelling and extension; Windows can hide extensions and leave a file named, for example,GTA5JetPack.dll.dll. - Check the loaders. Confirm that Script Hook V and ScriptHookVDotNet are installed for the same edition and build. Make sure NativeUI and the vehicle-spawning unblock dependency named by the mod page are present.
- Confirm the game build. The historical minimum is 1.42, but a current build still needs a compatible Script Hook V and SHVDN combination.
- Read the configured key. F5 is the default menu key, but the mod says it can be changed in
JetPackSettings.ini. Open the INI with a plain-text editor and use the key listed there. Avoid changing unrelated settings while diagnosing. - Check whether SHVDN discovered the file. When SHVDN is operational, its console’s
ListScripts()command can show loaded scripts. If the jetpack script is absent, focus on the folder, filename, loader and dependency checks; the list does not prove that the mod itself is compatible.
If the script appears in the list but F5 still has no effect, the likely branches are a changed key, a missing NativeUI dependency, a game-edition mismatch or a mod compatibility problem. Do not treat the absence of an error message as proof that every dependency is healthy.

What if the script is missing from ListScripts()?
When GTA5JetPack.dll is not listed, SHVDN did not load it. This narrows the problem to discovery and prerequisites rather than the in-game jetpack controls.
- Close the game and check the exact
scriptsdirectory again. - Confirm that the file is a DLL, not an archive still ending in
.zipor.rar, and that Windows has not appended a second extension. - Check that SHVDN itself loads by looking for its normal console or log output. If no SHVDN scripts appear, repair SHVDN before troubleshooting the jetpack file.
- Recheck NativeUI and the other dependency named on the mod listing, including their expected locations.
- Start a clean single-player session and run
ListScripts()again.
If other .NET scripts load but this one does not, compare the jetpack DLL’s path and filename with the archive contents. A file copied into a nested folder such as scriptsGTA5JetPackGTA5JetPack.dll may not be found when the loader expects the top level. The diagnostic command identifies discovery, not whether version 1.1 can run on your current build.
Why does pressing F5 not open the menu?
F5 is only the default. The INI can override it, and another script or overlay may already be using the same key.
- Open
JetPackSettings.iniin the samescriptsfolder as the DLL. - Find the menu-key setting and compare it with the key you press. Preserve the existing format and use a value accepted by the mod’s configuration.
- Save the file as plain text, restart the game and try the configured key in single-player.
- If the menu still does not appear, temporarily choose a key that is unlikely to be claimed by another script, then retest.
Do not assume a key change fixes a loader failure. If the DLL is absent from ListScripts(), resolve loading first. If it is present and the key is correct, investigate NativeUI, edition compatibility and the current game’s support for this 2020 script.
How do I fix a crash on startup after installing the mod?
A startup crash after adding the jetpack files is a change-isolation problem until logs or a reproducible cause show otherwise. The most common documented tool-level cause is a Script Hook V and game-build mismatch, especially after a Rockstar update.
- Back up saves and the installation.
- Remove or rename only the newest jetpack files, then launch single-player. Keep a record of exactly what you changed.
- If the game starts, check the official Script Hook V page for a release supporting your installed patch and verify that your Legacy or Enhanced edition uses the corresponding tool instructions.
- Reinstall the compatible loader and SHVDN components, then add the jetpack DLL, INI and required dependencies back one at a time.
- Launch after each addition. The first component that brings the crash back is the useful isolation point; it is not, by itself, proof that the component is defective on every setup.
Loose root files are commonly touched by mod installations, so do not delete unknown files without a backup and a way to restore them. If the game still crashes with the jetpack files removed, the update or another plugin is the more likely change and the jetpack script is not yet established as the cause.

Why did the game crash after a Rockstar update?
Script Hook V must match the executable patch. The modding guide explains that Script Hook V commonly stops working after a GTA V update until a compatible build is released. In that interval, a previously working .NET script can appear broken even though its two files have not changed.
- Record the GTA V build shown by your launcher or game files.
- Open the official Script Hook V release page and compare its supported patch numbers and release date with your build.
- Check whether your edition is Legacy or Enhanced and follow only its tool instructions.
- If no compatible Script Hook V release is listed, remove the modded loader from active use or wait rather than mixing files from different releases.
- Once the loader is confirmed compatible, add the jetpack script back and test only in single-player.
The current official page’s listed July 15, 2026 release supports 1.0.3889.0 / 1.0.1158.13 at the research date. Those numbers can change, and they do not certify GTA5 JetPack Mod 1.1, which was last updated in 2020.
What should I do if it works until a save loads, then crashes?
A crash after loading a save can involve a spawned vehicle, NPC configuration, another script or a damaged state rather than initial script discovery. Use a controlled rollback instead of changing several settings at once.
- Back up the affected save.
- Remove the jetpack DLL and test a fresh single-player session and the original save without it.
- If the save is stable, restore the DLL with the INI’s optional friendly/enemy NPC features disabled, if those settings are available, and test again.
- Add other plugins back one at a time, starting with the dependency the mod listing requires for vehicle spawning.
- If only one save crashes, use a clean save to separate save-state damage from a global loader problem.
This process identifies a correlation on your installation; without logs or a reproducible test it cannot establish a universal cause.

The available evidence cannot confirm that it does. The mod page is for version 1.1, updated June 3, 2020, and only states a minimum of version 1.42. The reviewed sources do not demonstrate compatibility with current Legacy or Enhanced builds or current ScriptHookVDotNet releases.
Use the evidence as a decision rule: if your edition’s compatible Script Hook V and SHVDN load other .NET scripts but JetPack Mod 1.1 remains absent or crashes, treat the mod as unverified on that build. Do not promise that installing the newest dependency will fix it. Keep a reversible backup, and consider an older supported game environment only if you can maintain it safely and within the game’s rules.

How can I perform a clean reinstall without losing the ability to roll back?
A clean reinstall means removing only this mod and its directly related dependencies, preserving a backup of every original file.
- Exit GTA V and the launcher.
- Copy the current
scriptsfolder and game-root loader files to a dated backup folder. - Remove
GTA5JetPack.dllandJetPackSettings.inifrom the activescriptsfolder. - Remove or restore only dependency files that you know belong to this setup; do not erase unrelated scripts.
- Launch unmodified single-player once. If it fails, repair the base installation through the platform launcher before adding mods.
- Install the edition-appropriate Script Hook V, SHVDN and NativeUI versions, then place the two jetpack files in
scripts. - Start the game, confirm discovery with
ListScripts()when available, and test the configured menu key.
Keep the dated backup until you have completed several launches. It is easier to restore a known state than to reconstruct which loose files were present.

- Putting the DLL in the root folder: that is the usual destination for an ASI plugin, not this .NET script.
- Installing every tool marked “latest”: a loader still has to support your exact game build and edition.
- Changing the INI before confirming loading: a key edit cannot make a missing DLL appear in SHVDN.
- Testing in GTA Online: Script Hook V is designed for custom single-player scripting and closes the game when entering multiplayer.
- Replacing files without a backup: this removes your easiest recovery path after an update or failed dependency swap.
- Assuming the 1.42 minimum is current support: it only explains why older builds lack the model.
Quick decision checklist
| Observed symptom | First checks | Likely next action |
|---|---|---|
| Jetpack script is absent from SHVDN’s list | Exact scripts path, DLL extension, SHVDN and NativeUI |
Correct the path or dependency chain, then relaunch |
| Script appears but F5 does nothing | JetPackSettings.ini key and menu conflicts |
Use the configured key; then investigate compatibility |
| Crash begins immediately after installation | Newest change, Script Hook V support for the game build | Remove the jetpack files, verify the loader, re-add components one at a time |
| Crash begins after a Rockstar update | Edition and patch numbers against the official Script Hook V page | Wait for or install a compatible loader release |
| Crash occurs only with one save | Clean save, NPC/vehicle settings and other scripts | Restore a backup and isolate save-state or plugin conflicts |
How do I know when to stop troubleshooting?
Stop adding files when the game cannot launch with a known-compatible loader, or when the only evidence available is a 2020 mod listing against a newer unsupported build. Keep the installation backed up, document the exact edition and patch, and wait for a compatibility statement or updated toolchain instead of repeatedly cycling random DLL versions.
The dependable facts are narrower than many forum fixes suggest: the two jetpack files go in scripts; the listing names Script Hook V, ScriptHookVDotNet, NativeUI and a vehicle-spawning unblock dependency; F5 is configurable; and Script Hook V must match the game build. Everything beyond those checks should be treated as an installation-specific diagnosis, not a guaranteed repair.
Frequently Asked Questions
Can I use GTA5 JetPack Mod [.NET] in GTA Online?
No. Treat it as a single-player mod. The official Script Hook V documentation says the tool closes GTA V when a player enters multiplayer, and the installation guidance warns against loading mods online.
Does reinstalling the newest Script Hook V guarantee that the jetpack mod will work?
No. Script Hook V still has to support your exact GTA V patch and edition, and the jetpack listing has not been shown to support current builds. A compatible loader removes one possible failure, but it cannot establish compatibility for a 2020 script.
Why is the jetpack menu key different from F5 on my PC?
F5 is the default only. Open JetPackSettings.ini beside the DLL and check the configured menu key; another script or an edited INI may have changed it.
What does an empty SHVDN script list tell me?
It indicates that SHVDN did not discover that script, so check the active installation path, filename and loader dependencies first. It does not prove that the mod is compatible once it is discovered.
Should I downgrade GTA V to version 1.42?
The mod page’s 1.42 figure is a historical minimum tied to the jetpack model, not a recommendation to downgrade. Downgrading can create separate launcher, save and security problems; first verify the edition-specific loader support for your installed build.
