“The program can’t start because w1import.dll is missing from your computer.”
The w1import.dll error belongs to The Witcher 2: Assassins of Kings, not to Windows itself. The safest repair is to verify or repair the game installation so its original DLL is restored to the game’s bin folder.

Which fix applies to you
Use the first matching description:
- The message says the file is missing or was not found: verify or repair The Witcher 2 through Steam, GOG Galaxy, or Epic.
- The file exists, but Windows says it could not be loaded: repair the installation, check for an incomplete patch, and inspect antivirus quarantine.
- The message mentions
0xc000007b,mfc100u.dll,msvcr100.dll, or another runtime: repair the relevant 32-bit Visual C++ packages instead of replacingw1import.dll. - The game crashes after the opening sequence while importing The Witcher 1 saves: test the save-import workaround described below.
- The error names
d3dx9_*.dllor another DirectX component: install Microsoft’s legacy DirectX runtime. - A broader set of games or applications also fails: investigate Windows system files or graphics drivers. Those repairs do not recreate this game DLL.
What w1import.dll is and where it belongs
w1import.dll is a private 32-bit game DLL used by The Witcher 2, including its Enhanced Edition and store releases. CD PROJEKT RED’s technical information identifies it as a game file that belongs in the installation’s bin directory.
On a typical Steam installation, that location is similar to:
#1 Best Overall
- The Witcher 2: Assassins Of Kings is a single player Role Playing Game (RPG), and sequel to the critically acclaimed 2007 PC game, The Witcher.
- Assassins Of Kings continues the adventures of the Medieval monster hunter for hire, Geralt of Rivia, and his search for the truth of his forgotten past and the treachery surrounding him.
- Game features include: hack n' slash and magical combat, a mature storyline, game development based on choices in mission play and dialog chains and weapons variety.
- Sequel to the acclaimed 2007 PC RPG, The Witcher 2: Assassins of Kings continues the adventures of Geralt of Rivia
- A complex, expansive and mature adventure with a non-linear story in which every decision may have grave consequences
C:Program Files (x86)Steamsteamappscommonthe witcher 2bin
The file should sit beside witcher2.exe. Your library may be installed on another drive or under a different folder.
The DLL supports the game’s The Witcher 1 save-import feature. Its observed W1CanImport export is consistent with that role, although this is not a current official support description.
It is not:
- A Windows system DLL
- A Microsoft runtime
- A graphics-driver file
- A file that belongs in
C:WindowsSystem32 - A DLL that normally needs registry registration
A missing message usually means the file was deleted, quarantined, or never installed correctly. A load failure can also mean that the DLL is damaged, belongs to the wrong edition, or depends on another unavailable component.
Fix 1: Verify the game installation
This is the highest-probability repair because the store client can restore the correct file for your edition.
Recommended Free Tools
Steam
- Open Steam and select Library.
- Right-click The Witcher 2: Assassins of Kings.
- Select Properties.
- Open Installed Files.
- Select Verify integrity of game files.
- Wait for Steam to finish.
- Start the game again from Steam.
Steam may report that files were reacquired or replaced. Check the game’s bin folder afterward if the error remains. The expected result is a restored w1import.dll beside witcher2.exe.
GOG Galaxy
- Open GOG Galaxy.
- Select The Witcher 2.
- Select Customize.
- Choose Manage installation.
- Select Verify/Repair.
- Allow the process to complete.
- Launch the game again.
Epic Games Launcher
- Open Epic Games Launcher.
- Select Library.
- Find The Witcher 2.
- Select the three dots beside the game.
- Choose Manage.
- Select Verify.
- Start the game after verification finishes.
If verification reports no problem but the file is still absent, close the launcher completely and repeat the repair once. If the file continues to disappear, check antivirus quarantine before reinstalling.
Fix 2: Repair the edition or apply the correct official patch
Old disc installations and partially updated Enhanced Edition installations can contain an incomplete or mismatched set of files.
For Steam, update through Steam. Do not apply a disc-oriented patch manually to a Steam copy.
Free tools Windows power users keep installed
One-click scans. No signup required.
Rank #2
- You will need a plan to make accurate decisions and think through combat tactics. Over-reliance on your reflexes is what will get you killed
- Uncontested swordsmanship, uncanny night vision, unrivalled knowledge of alchemy, and ability to spark desire in women and trepidation amongst foes
- Training, trials and tribulations let you tap into supernatural abilities that have mutated your organism
- Non-linear Decisions and Consequences
- A vast set of choices, each with it own impact on the fate of the fantasy world. Retracing your steps with different decisions will unlock alternative endings and previously unseen sequences
For a disc installation:
- Confirm which edition you own.
- Download the correct update from CD PROJEKT RED’s official The Witcher 2 support page.
- Follow the complete manual-update instructions for that edition.
- Keep all required patch parts in the same folder.
- Run the supplied
Patch.exeas instructed. - Restart Windows and launch the game.
CD PROJEKT RED’s current manual-update material lists the Enhanced Edition patch and patches 3.1, 3.2, and 3.3. Patch 3.4 is delivered through automatic update. Do not mix files from unrelated releases.
If the patch process fails, uninstall the game, restart Windows, reinstall it from the original store or disc media, and apply only updates intended for that edition.
Fix 3: Check Windows Security quarantine
Antivirus software can remove or quarantine a game DLL after an update or scan.
- Open Windows Security.
- Select Virus & threat protection.
- Choose Protection history.
- Look for an entry involving
w1import.dllor the game folder. - Expand the entry and review its path and detection details.
Restore the file only if all of these are true:
- It came from the legitimate game installation.
- The path is the expected The Witcher 2 folder.
- You can confirm the alert is a false positive.
- You will immediately verify or repair the game afterward.
Do not permanently disable antivirus protection to make the game launch. If the file was obtained from an unofficial DLL archive, delete it and reinstall the game from the store or original media instead.

A crash after the intro is different from a missing-file dialog. In this case, w1import.dll may be the module handling a problematic or unusually large collection of The Witcher 1 saves.
Back up your saves first. Then:
- Exit the game and the launcher.
- Open File Explorer.
- Browse to:
text
DocumentsThe Witcher
- Make a copy of that folder somewhere safe.
- Rename the original folder to something like
The Witcher backup. - Launch The Witcher 2 and test the opening sequence.
If the crash stops, restore only a known-good save or a smaller set of saves and test again. If cloud synchronization restores the removed files, temporarily disable synchronization while testing.
This is a community workaround, not a confirmed official diagnosis. Do not delete the backup until your saves are safely recovered.
Fix 5: Repair Visual C++ only for dependency errors
Do not install Visual C++ packages merely because w1import.dll is missing. Use this branch when the message also names:
Rank #3
- New system of Mutagens gives you the ability to modify the effects of particular skills
- An engrossing, mature storyline defining new standards for realistic, non-linear game narration
- Enhanced RPG Experience for deeper story and role-playing Extensive non-linearity, unique inter-connected quest-lines and greatly enhanced characters
- You could enhance and modify the way your spells work, by multiplying the damage - be it greater amount, or dealing with more enemies at the same time
- Advanced new customization mechanics vastly increased the possibilities for you to modify your weapons, armor and spells
0xc000007bmfc100u.dllmsvcr100.dll- Another Visual C++ or runtime dependency
CD PROJEKT RED’s launch guidance refers to the legacy Microsoft Visual C++ 2005, 2008, and 2010 packages. On 32-bit Windows, install the x86 packages. On 64-bit Windows, install the x86 packages because this game is 32-bit; installing the x64 packages as well may be appropriate for other software.
Use Microsoft’s official downloads for:
- Microsoft Visual C++ 2005 Redistributable
- Microsoft Visual C++ 2008 Redistributable
- Microsoft Visual C++ 2010 SP1 Redistributable/MFC Security Update
Restart Windows after installation and launch the game again. Installing only the newest unified Visual C++ package does not necessarily provide every legacy runtime required by an older game.
Fix 6: Install legacy DirectX components for DirectX errors
Use this step only when the error names d3dx9_*.dll, d3d9.dll, or another DirectX component.
- Download Microsoft’s DirectX End-User Runtime Web Installer,
dxwebsetup.exe. - Run the installer.
- Accept the license terms.
- Let it install the legacy side-by-side components.
- Restart Windows.
- Launch the game.
This package supplies older game components. It does not replace the core DirectX version built into Windows, and it does not restore w1import.dll.

SFC and DISM repair Windows system files and the Windows image. They do not reinstall third-party game files, so they are not the first response to this error.
Use them when Windows has broader symptoms, such as damaged system components, failed Windows features, or multiple unrelated applications failing.
- Open Start and type
Command Prompt. - Right-click Command Prompt.
- Select Run as administrator.
- Run:
text
DISM.exe /Online /Cleanup-image /Restorehealth
- Wait for it to complete.
- Run:
text
sfc /scannow
- Restart Windows.
Success means DISM or SFC reports that repairs were completed, or that no integrity violations were found. If the commands report that they could not complete, address the Windows repair error separately and still verify or reinstall The Witcher 2.
Rank #4
- Assassins of Kings continues the adventures of the Medieval monster hunter for hire, Geralt of Rivia, and his search for the truth of his forgotten past and the treachery surrounding him.
- Game features include: hack n' slash and magical combat, a mature storyline, game development based on choices in mission play and dialog chains and weapons variety.
- Spectacular, dynamic, brutal combat system featuring numerous tactical options such as, real-time interactive moves, ranged weapons, traps and bait and non-lethal attacks.
When manually running SFC and DISM means repeating scans without knowing which Windows component changed, Outbyte PC Repair can show what its scan identifies; its repair functions require the full version, and reinstalling The Witcher 2 remains the definitive fix for this game DLL.
System Restore is a last resort after a recent system change:
- Press
Windows+R. - Enter
rstrui.exe. - Select a restore point from before the problem began.
- Review the affected programs.
- Follow the wizard to restore Windows.
It reverts system configuration and installed programs. It does not replace a normal game repair.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Fix 8: Update or reinstall graphics drivers only for broader crashes
A graphics-driver repair is relevant when several games crash, the display driver is failing, or the game reports a graphics initialization problem. It does not recreate w1import.dll.
To check the current driver:
- Right-click Start.
- Select Device Manager.
- Expand Display adapters.
- Right-click the graphics adapter.
- Select Properties and open the Driver tab.
- Record the adapter and driver details.
- Download the correct driver from the GPU manufacturer.
- Install it using the manufacturer’s clean-install option when available.
- Restart Windows.
If you use Device Manager’s Update driver option, choose Search automatically for drivers. If it finds nothing, use the manufacturer’s official support page rather than a random driver archive.
When identifying the correct driver manually means hunting through many versions and guessing which component is stale, Outbyte Driver Updater can scan and identify driver issues; installation through its full version is optional, and it does not replace repairing the game installation.
Do not copy the DLL or use regsvr32
Avoid DLL download websites. A replacement can contain malware, belong to the wrong game edition, use the wrong architecture, or simply hide the damaged installation that caused the error.
If you have a verified copy from the same legitimate edition, manual copying is appropriate only in the narrow case where it is restored to that edition’s bin folder beside witcher2.exe. Never copy it to System32 or SysWOW64.

FAQ
Is w1import.dll safe?
The legitimate file is a The Witcher 2 game component. Its safety depends on where it came from. A copy restored by Steam, GOG Galaxy, Epic, the original disc installation, or an official CD PROJEKT RED update is the appropriate source.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteShould I download w1import.dll separately?
No. Verify, repair, or reinstall the game instead. Random DLL sites can provide an altered, incompatible, or incorrectly matched file.
Does it belong in System32?
No. It belongs in the game’s bin folder beside witcher2.exe.
Will Visual C++ fix a missing w1import.dll?
Not directly. Visual C++ applies when the error names a runtime dependency or 0xc000007b. The game client or official installer must restore the missing game file.
Why does the crash happen after the intro?
The game may be processing The Witcher 1 saves. Back up the save folder, temporarily rename it, and test with no imported saves. Treat this as a troubleshooting workaround rather than an official fix.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Do I need to register the DLL?
No. Do not use regsvr32 for this private game DLL.
Should I run SFC or DISM first?
Only when Windows itself shows wider corruption. For a w1import.dll error limited to The Witcher 2, verify or reinstall the game first.
