To verify Total War: SHOGUN 2 – Complete Edition on Steam, open your Library, right-click the game, choose Properties, select Installed Files, and click Verify integrity of game files. If the game still crashes, check the edition and mod setup before moving on to Steam Overlay, Windows and graphics-driver updates, Visual C++ components, GPU power settings, and a backed-up test of the game’s preferences and cached data. These are diagnostic steps, not guaranteed fixes.
Edition matters: SEGA says Complete Edition has integrated Mod.io support and that mods made for the original SHOGUN 2 are not compatible. Confirm which edition you have before following advice about Steam Workshop mods or removing files.

How do I verify SHOGUN 2 Complete Edition files on Steam?
Use Steam’s built-in verification option. It checks the game’s installed files and can replace files Steam identifies as missing or damaged; it does not diagnose every possible cause of a crash.
- Open Steam and go to Library.
- Right-click Total War: SHOGUN 2 – Complete Edition in your game list.
- Choose Properties.
- Select Installed Files.
- Click Verify integrity of game files and wait for Steam to finish.
SEGA gives this route in its Steam troubleshooting guide. Let the check complete before launching the game or deciding that verification made no difference. If Steam reports that files needed replacing, allow it to finish the repair, then launch the game and see whether the original crash still occurs.

Keep the result in context: verification concerns the installed game files, while the user folder under Roaming and mod state are separate things to investigate. A completed check is useful whether or not Steam replaces anything; it rules out only the file problem this check can address. It does not establish that a crash is caused by a mod, a driver, or saved preferences, nor does it promise to repair every cause.
If verification completes but the crash remains, do not simply repeat the same check as though it were a universal repair. A crash can persist because of mods, Steam Overlay, Windows or graphics drivers, Visual C++ components, a GPU power setting, or saved preferences and cached data. Work through the checks below one at a time so you can tell whether a change affects the problem.
How can I confirm which SHOGUN 2 edition and mod system I have?
Confirm the installed edition before changing mods or deleting mod files. The Complete Edition and original SHOGUN 2 do not share the same mod compatibility described by SEGA.
SEGA describes Complete Edition as an updated and enhanced PC version that includes the original game and associated DLC. Its Complete Edition FAQ says it has integrated in-game mod support through Mod.io and that mods made for original SHOGUN 2 are incompatible with Complete Edition. That means original-game Workshop instructions should not automatically be applied to Complete Edition. If you are unsure which edition Steam installed, check the game’s name and edition information in your Steam Library and compare it with SEGA’s FAQ before altering files.
SEGA’s separate instructions for the original game discuss Steam Workshop subscriptions and files in the game’s data folder and Steam Workshop content folder. Those instructions are relevant to an original-game installation, not proof that Complete Edition uses the same mod workflow. Avoid mixing the two branches: first identify the edition, then use the support guidance that matches it.
This distinction matters even if the game launches and only crashes later. The presence of a mod or a Workshop subscription does not by itself show that it is compatible with Complete Edition. Treat edition and mod system as the first comparison, then test changes only within the branch that applies to your installation.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
What should I do if the crash may be mod-related?
Use mod isolation as a controlled diagnostic step, while protecting saves and respecting the edition distinction. For Complete Edition, do not treat mods made for the original game as compatible; for the original game, inspect Workshop subscriptions and leftover files as SEGA describes.
If you have Complete Edition
Check whether you have added or enabled mods through the Complete Edition’s supported mod system. SEGA’s FAQ identifies integrated Mod.io support and says original SHOGUN 2 mods are incompatible. If a crash began after changing mods, temporarily remove or disable the relevant Complete Edition mod using the options available in that game’s supported mod interface, then launch again. Do not use the original game’s Workshop folder instructions as a substitute for Complete Edition-specific guidance.

When testing, note which mod state you changed and whether the same crash returns. If the test changes nothing, restore the prior state if appropriate and continue; it does not prove that all mod-related possibilities have been ruled out. The official guidance establishes the edition incompatibility, but it does not provide a Complete Edition-specific folder-cleanup procedure to use in place of its supported interface.
If you have the original SHOGUN 2
SEGA’s mod-removal article advises checking the mod list in the launcher or Steam’s subscribed items, deactivating or unsubscribing from mods, and checking for leftover files in the game’s data folder and Steam Workshop content folder. After removing mods, verify the game files again through Steam.
Back up saves before changing mod state. SEGA warns that a current save may depend on a mod; removing that mod can mean the campaign will not continue as before, and a new campaign may be needed. Do not delete saves to test a mod problem. Change one mod-related variable at a time and note whether the crash changes. SEGA says that if unsubscribing from or deleting mods resolves the issue, it is almost certainly mod-related, but that does not identify which mod caused it.
For current instructions, see SEGA’s guide to identifying and uninstalling mods. Although its procedures focus on original SHOGUN 2 and Workshop content, the edition compatibility warning remains important when diagnosing Complete Edition.
Which Steam and Windows settings should I check next?
If file verification and an appropriate mod check do not change the crash, follow SEGA’s broader Steam troubleshooting checks: test with Steam Overlay disabled, update Windows and graphics drivers, check Visual C++ components, and inspect the game’s GPU power setting.
Test with Steam Overlay disabled
SEGA recommends testing the game with Steam Overlay disabled. Treat this as a temporary diagnostic change: disable the overlay, launch SHOGUN 2, and see whether the same crash occurs. If it does, restore the setting if you want it enabled and continue to the next check. If the symptom changes, record that result rather than assuming the overlay is conclusively responsible.
Recommended Free Tools
Install available Windows and graphics-driver updates
Check Windows Update for available updates, and check the support channel for your graphics hardware for an appropriate driver update. SEGA lists both Windows updates and graphics-driver updates among its troubleshooting steps. Avoid treating “latest” as a reason to install a driver from an unrelated download site; use the applicable official update route for your Windows installation and graphics hardware.
Complete the update process, including any restart Windows requests, before comparing results. Otherwise, you may be testing the game before the update has taken effect. Record which update you applied and whether the crash behavior changed; if it did not, move to the next check rather than layering several untracked changes together.

Check Visual C++ components
SEGA directs players to check the required Visual C++ components in Steam’s Steamworks Shared_CommonRedistvcredist folder. Open the relevant folder in the Steam installation and check the components available there against SEGA’s current troubleshooting instructions. Do not download an arbitrary package or remove installed components as a guess; the source guidance is to check the required components, not to indiscriminately replace system libraries.
Check the GPU power setting
SEGA also advises checking that the game’s GPU power setting is not forcing an unsuitable power-saving mode. The exact control-panel labels vary by graphics hardware and software, so use the settings for your own GPU rather than following a path for a different vendor. Test a suitable performance-oriented setting for the game, then see whether the crash behavior changes. This is a diagnostic check, not a guarantee of a fix.
Free tools Windows power users keep installed
One-click scans. No signup required.
SEGA’s Steam troubleshooting page collects these checks. Windows or driver updates may require a restart; finish the update process before comparing the game’s behavior.
Should I try administrator permissions or change the game version?
SEGA’s Steam guide also describes testing the game executable as an administrator and confirming Steam is using the default public version rather than an older beta. These are checks, not guaranteed crash fixes.
To test permissions, locate the game executable in its installation and use its Windows option to run as administrator. Try this only as a diagnostic comparison; if it does not alter the crash, return to your usual launch method. Avoid changing unrelated permissions or making permanent system-wide changes without a specific reason.
Also check that the game is set to the default public version in Steam rather than an older beta branch. Beta selection can change which build launches, so record the current setting before changing it. The support guidance does not establish that a beta branch is the cause of any particular crash; the point is to rule out an unintended version selection while troubleshooting.

Do not infer that administrator access or a beta selection caused the problem merely because changing it coincides with a different outcome; the support article offers these as troubleshooting checks, not a symptom-specific diagnosis.
How do I test a clean preferences and cache folder safely?
Test a clean user-data folder only after the earlier checks, and back up the relevant files first. SEGA’s general troubleshooting guidance describes temporarily moving the relevant game folder from the Creative Assembly folder under %AppData%Roaming, then starting the game.

- Close SHOGUN 2 and Steam before changing user files.
- Open the Roaming location by entering
%AppData%Roamingin File Explorer’s address bar. - Back up the relevant game folder under
Creative Assemblyto a separate location. Do not delete it. - Temporarily move that game folder out of the Roaming location.
- Start the game and check whether it behaves differently with a fresh folder.
If the game starts or the crash changes, the saved user folder may be involved, but this test does not by itself identify a particular file or setting. SEGA says that if the test works, the saved game folder can be used to copy saves back. Restore files carefully and incrementally; copying the entire old folder back at once can reintroduce the configuration or cached data you were trying to isolate. Keep the backup until you have confirmed which files you need.
Compare like with like: if the original problem occurred at launch, test whether launch behavior changes; if it occurred while loading or during play, repeat that same kind of test when possible. SEGA does not supply a SHOGUN 2-specific crash-stage diagnosis, so a different result can point to user data being relevant without proving which saved setting or file is responsible.
This is why moving the folder is preferable to deleting it: it gives you a reversible test and preserves a route back to your saves. SEGA’s general troubleshooting guidance includes file verification, updates, mod checks, and this AppData test. Do not treat user data deletion as a first-line fix.
What should I record before contacting SEGA Support?
If the crash remains after verification and the relevant troubleshooting checks, send SEGA Support useful diagnostic information rather than continuing to make untracked changes. SEGA’s mod support article recommends submitting a support request with a DxDiag report and, when possible, the latest .mdmp file.
In the request, identify that the game is SHOGUN 2 – Complete Edition or the original game, describe when the crash occurs (for example, at launch, while loading, or during play), and list the checks you completed and what changed. These details help distinguish a file-verification result from a mod, setting, or configuration test. Do not claim a particular cause based only on the crash stage: SEGA does not provide a SHOGUN 2-specific symptom-to-cause matrix in the cited troubleshooting guidance.
Attach DxDiag and the latest available .mdmp if you can provide them, and submit the request through SEGA Support. The support route is the appropriate next step when the general checks do not resolve the issue; none of the listed steps guarantees that every crash can be fixed locally.

- Verify files in Steam. Complete the Installed Files integrity check first.
- Confirm the edition. Complete Edition uses integrated Mod.io support and is not compatible with original-game mods, according to SEGA.
- Isolate mods carefully. Follow the relevant edition’s procedure and protect mod-dependent saves.
- Check the Steam and system factors. Test Overlay disabled; check Windows and graphics-driver updates, Visual C++ components, and GPU power selection.
- Check version and permissions. Confirm the default public version and, as a diagnostic, test running the executable as administrator.
- Test user data reversibly. Back up and temporarily move the relevant folder under RoamingCreative Assembly; do not delete it.
- Escalate with diagnostics. If the problem persists, contact SEGA with DxDiag and the latest
.mdmpwhere possible.
Record each change and the result before moving on. If several settings, mods, and files are changed at once, a changed symptom will be harder to interpret and the original state will be harder to restore.
There is no official SHOGUN 2-specific table that maps a crash at launch, a loading crash, or an in-game crash to one confirmed fix. Use the stage to describe and reproduce the problem, not as proof of its cause. The practical comparison is whether the same scenario changes after a controlled test: first verify the files, then isolate the edition-appropriate mod state, and continue through the reversible checks.
Frequently Asked Questions
Will verifying SHOGUN 2 files remove my saves?
SEGA’s troubleshooting sequence treats the installed game files and the saved game folder under Roaming as separate things, and recommends backing up that folder before a clean-folder test. Keep a separate save backup before changing mods or user data; do not assume any troubleshooting operation is a substitute for a backup.
Does Complete Edition use the Steam Workshop for mods?
SEGA’s Complete Edition FAQ identifies integrated Mod.io support, while its Workshop subscription and folder-removal instructions concern the original SHOGUN 2. If you are unsure which edition or mod workflow applies, confirm the edition and follow its support guidance rather than importing the original game’s instructions.
Should I reinstall the game if Steam verification does not stop the crash?
SEGA’s cited troubleshooting guidance recommends checking mods, Steam and Windows factors, and user configuration after verifying files; it does not present reinstalling as a guaranteed next step. Work through those reversible checks first, and contact SEGA Support if the crash persists.
What is a .mdmp file, and do I need one for a support request?
It is a crash-dump file that may be available after a crash. SEGA recommends including the latest .mdmp when possible, alongside DxDiag; the wording makes it helpful when available rather than a prerequisite for asking Support for help.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsDoes the point where SHOGUN 2 crashes identify the cause?
No confirmed crash-stage-to-cause matrix is provided in SEGA’s cited guidance. Record whether it happens at launch, while loading, or during play so Support can understand the symptom, but use the troubleshooting checks rather than treating the stage as a diagnosis.
