What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
If libgomp-1.dll is missing, repair or reinstall the application, plugin, or game that reported the error rather than downloading an isolated DLL. libgomp-1.dll is a GCC-based runtime, so the correct file depends on the failing program’s architecture, toolchain, and bundled dependencies.
What this file actually does
libgomp-1.dll is the Windows runtime library for GNU OpenMP and OpenACC. GCC-built applications use it to run parallel code, commonly when they were compiled with GCC’s -fopenmp option.
As an Amazon Associate I earn from qualifying purchases.
It is supplied by GCC-based toolchains such as MinGW-w64 and MSYS2, or bundled inside applications built with those toolchains. It is not a Windows system DLL and is not normally installed in C:WindowsSystem32 or C:WindowsSysWOW64.

Cause-by-symptom guide
| Message or symptom | What it usually means | Best first action |
|---|---|---|
| “The program can’t start because libgomp-1.dll is missing from your computer.” | The application cannot find its GCC OpenMP runtime. | Repair or reinstall the named application. |
| “The code execution cannot proceed because libgomp-1.dll was not found.” | The file is absent from the application bundle or its runtime search path. | Restore the matching application package. |
| “Unable to start … because libgomp-1.dll is missing.” | An application or plugin installation is incomplete or damaged. | Reinstall the parent program or plugin. |
| “Error loading libgomp-1.dll. The specified module could not be found.” | libgomp-1.dll, or one of its dependencies, may be missing. |
Reinstall the complete runtime bundle and check dependencies. |
| “libgomp-1.dll is either not designed to run on Windows or it contains an error.” | The DLL may be corrupt or built for the wrong architecture. | Remove stray copies and reinstall the matching build. |
“The procedure entry point GOMP_parallel could not be located…” |
Windows found a DLL, but it is the wrong version or incompatible with the application. | Find and remove the duplicate or incorrect runtime. |
The problem can appear after a fresh installation, an incomplete update, moving a portable application, extracting only an executable from a developer build, installing a plugin for the wrong host version, or antivirus quarantine. It can also result from mixing 32-bit and 64-bit components.
Fix 1: Identify and repair the application named in the error
Start with the executable shown in the dialog. It may be an image editor, scientific program, game, plugin host, Qt application, or a program you compiled yourself. Windows does not decide which libgomp-1.dll belongs there; the parent application does.
- Write down the exact program or plugin named in the error.
- Close the error and exit the application’s launcher.
- Open the product’s official website or its official launcher.
- Download the installer for the same product and architecture.
- Run the installer.
- Choose Repair if that option is offered.
- If there is no repair option, uninstall the application, restart Windows, and install it again.
- Launch the program from its normal shortcut or launcher.
For a game, open its launcher and look for Verify files, Repair, or an equivalent option. This restores files from the game’s own distribution instead of placing an unrelated DLL into Windows.
The repair worked if the application opens without the libgomp-1.dll message. If the same error remains, do not copy a random DLL into System32. Continue with the architecture and antivirus checks below.
For GIMP or a G’MIC-related failure, reinstall GIMP and the matching G’MIC plugin from their official installers. A 32-bit plugin must match a 32-bit host, and a 64-bit plugin must match a 64-bit host.
Fix 2: Match the application’s 32-bit or 64-bit architecture
A 64-bit Windows installation can run both 32-bit and 64-bit applications. That does not make their DLLs interchangeable.
Check the application’s download options, installer name, documentation, or vendor support information. If the error began after installing a plugin or add-on, check the host application and plugin separately.

Then:

- Download the build matching the host program.
- Install the plugin into the host’s normal plugin location.
- Start the host application again.
If a 32-bit program loads a 64-bit libgomp-1.dll, Windows usually reports that the file is invalid or not designed to run on Windows. If a program reports an entry-point error, it may have loaded a different, incompatible copy rather than finding nothing.
Do not assume that placing both copies in a common folder will solve this. Windows’ DLL search order can select an unintended copy from the application directory or a configured runtime path.
Fix 3: Check for duplicate or stray GCC runtimes
A working libgomp-1.dll can still cause an error if an older or incompatible copy is found first.
Check the application’s own installation directory and any custom GCC, MinGW, or MSYS2 directories you added to PATH. Do not delete files from a toolchain you still use without confirming which application needs them.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesA safer procedure is:
- Close the affected application.
- Open the application’s installation folder.
- Look for duplicate GCC runtime files supplied by older installations or manually copied packages.
- Move suspicious, manually added copies to a temporary backup folder rather than deleting them immediately.
- Re-run the application’s official installer or repair process.
- Start the program again.
The correct result is that the application uses the runtime shipped with its own installation or with the matching toolchain. If the error changes to a missing dependency message, reinstall the complete application package rather than adding DLLs individually.
Windows documents the DLL search process and the security risks of unsafe DLL search paths. Never place an arbitrary download in System32, SysWOW64, or a global PATH.
Fix 4: Check antivirus quarantine
Security software can remove or quarantine a runtime file after an application update or extraction.

In Windows Security:
- Open Start and search for Windows Security.
- Select Virus & threat protection.
- Select Protection history.
- Find the event involving the application or
libgomp-1.dll. - Confirm that the original application came from its legitimate vendor or official launcher.
- If it is confirmed legitimate, use the available restore or allow action.
- Reinstall or repair the application afterward.
Microsoft’s guidance for restoring quarantined files is available through its Defender quarantine instructions.
Do not restore a file merely because its name matches the error. If the source is uncertain, remove the application and reinstall it from the vendor’s official download. Use a narrow exclusion only when you have verified the application and understand why the detection occurred.
Fix 5: Repair a developer or MSYS2 installation
This step is for developers and packagers, not for downloading a generic DLL.
MSYS2 supplies the 64-bit runtime through the mingw-w64-x86_64-gcc-libs package. A normal MSYS2 development installation can be updated and repaired from an MSYS2 terminal:
pacman -Syu
pacman -S mingw-w64-x86_64-gcc
The exact package depends on the environment. A mingw32, ucrt64, clang64, or other MSYS2 environment must use its corresponding package family. Do not mix runtime directories between environments.
The Tool Desk
Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →For a packaged application, deploy libgomp-1.dll from the same toolchain that built the executable. In a 64-bit MSYS2 MinGW environment, the file is supplied under the environment’s bin directory. Copying only the named DLL may not be enough because the program can require other GCC runtime files as well.
The reliable developer fix is to:
- Identify the compiler and MSYS2 environment used to build the executable.
- Install or repair that exact GCC package family.
- Build or package the application with its required runtime files.
- Place matching runtime files beside the application executable, or configure a controlled runtime path.
- Test the packaged application on a clean machine.
If the program was obtained from someone else, ask that developer or vendor for a complete build rather than assembling its dependencies manually.

Fix 6: Separate libgomp errors from Microsoft runtime errors
Microsoft Visual C++ Redistributable does not install libgomp-1.dll. It supplies Microsoft runtime files such as vcruntime and msvcp.
Install the current supported Visual C++ package only if the same application separately reports a missing Microsoft runtime. It will not repair a missing GCC OpenMP library.
If the application shows both errors, install the Microsoft package from its official source, then repair the application so its GCC runtime is restored separately.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Fix 7: Repair broader Windows corruption only when appropriate
libgomp-1.dll is normally a third-party application file, so System File Checker is not the primary repair. SFC will not normally download a missing copy from the internet.
Use these commands when several Windows components are failing or corruption is suspected:
- Open Start.
- Search for Command Prompt.
- Select Run as administrator.
- Run:
DISM.exe /Online /Cleanup-image /Restorehealth
- Wait for it to finish.
- Run:
sfc /scannow
- Restart Windows and test the application again.
Microsoft recommends running DISM before SFC. Its System File Checker guidance explains the process.
Repeating these commands will not replace a missing application-bundled DLL. If Windows reports that it found no integrity violations, return to the parent application’s installer.

When hunting through Windows components and repeatedly guessing whether corruption is involved, Outbyte PC Repair can scan for problems and show what needs attention; its repair functions require the full version, but it is not required and reinstalling the affected application remains the definitive fix.
Fix 8: Update drivers only for a wider application failure
A graphics or device driver is not the normal source of libgomp-1.dll, and Device Manager cannot restore this runtime. Still, update drivers if the application also crashes with graphics, hardware, or device errors.
- Right-click Start and select Device Manager.
- Expand the relevant category, such as Display adapters.
- Right-click the device.
- Select Update driver.
- Choose Search automatically for drivers.
- Restart Windows if a driver is installed.
- Test the application again.
For the most reliable result, use the hardware manufacturer’s official driver package and select the correct Windows architecture. Do not expect a driver update to fix a standalone missing-runtime message.
Manually checking each Device Manager category can mean hunting through many driver versions and repeating installs without knowing what changed. Outbyte Driver Updater can scan and identify outdated drivers, while the full version performs driver installation; it is optional and does not replace repairing the application that owns libgomp-1.dll.
What not to do
- Do not download
libgomp-1.dllfrom a random DLL website. The file may contain malware, use the wrong architecture, belong to another GCC build, or leave the actual missing dependency untouched. - Do not copy it into
System32orSysWOW64. - Do not add an arbitrary DLL directory to the global
PATH. - Do not use
regsvr32on it.libgomp-1.dllis generally a runtime library, not a COM or ActiveX component.regsvr32is intended for DLLs that exportDllRegisterServer. - Do not install Visual C++ Redistributable as a substitute for the GCC runtime.
- Do not mix MinGW, MSYS2, UCRT, and other toolchain runtime folders.
When “module not found” is not libgomp itself
The message “The specified module could not be found” can mean that Windows found libgomp-1.dll but could not load one of its dependencies. An entry-point error usually means the wrong runtime version was loaded.
If reinstalling the parent application fails:
- Confirm the exact executable that starts the error.
- Check the application’s architecture.
- Review antivirus Protection history.
- Remove manually copied or duplicate runtime files.
- Use a reputable local dependency-analysis tool to identify the missing dependency.
- Contact the application vendor with the exact error and executable name.
Do not keep replacing DLLs blindly. The correct repair is the complete, matching application or toolchain package.
FAQ
Is libgomp-1.dll part of Windows?
No. It comes from GCC-based toolchains or an application built with them.

A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11Where should I install it?
Normally, it should be installed or restored beside the application that needs it, as part of that application’s official package. Do not place it in a Windows system folder.
Will Microsoft Visual C++ Redistributable fix it?
No. That package supplies Microsoft runtime files, not GNU libgomp-1.dll.
Does a 64-bit PC need the 64-bit DLL?
Not always. The required DLL matches the application. A 32-bit program needs a 32-bit runtime even on 64-bit Windows.
Should I register it with regsvr32?
No. This runtime library is not normally a registered COM component, so regsvr32 is not a repair method.
