“The program can’t start because msoxev.dll is missing from your computer.” The msoxev.dll file is a Microsoft Office InfoPath component, so the safest fix is to repair or reinstall the Office product that supplied it.
Which fix applies to you
Use this list to choose the right starting point:
- The error appeared while opening InfoPath or an Office form: repair Microsoft Office first.
- InfoPath or an older Office edition was recently removed: reinstall the licensed Office or InfoPath product that still needs the file.
- Windows Security shows a recent detection: investigate Protection history before restoring anything.
- The message says “specified module could not be found”: the named file or one of its dependencies may be missing.
- The error began after an update, cleanup, or system change: consider System Restore after checking Office repair.
- Several Windows programs are also failing: run DISM and SFC, but do not expect them to recreate an Office-owned DLL.
- The file exists but will not load: verify its location, digital signature, Office architecture, and the application named in the error.
- The message asks you to register the DLL: do not begin with a generic
regsvr32command. Office repair is normally the correct remedy.
What is msoxev.dll
msoxev.dll is a Microsoft Office InfoPath file. Its internal description is XEV, and its publisher is Microsoft Corporation. It is an Office application component, not a core Windows DLL.
It may be found beneath an Office installation directory, including versioned folders such as OFFICE11, OFFICE12, OFFICE15, or OFFICE16. A documented Office 16 installation places a 32-bit copy below a path similar to:
C:Program Files (x86)Microsoft OfficerootvfsProgramFilesCommonX86Microsoft SharedOFFICE16MSOXEV.DLL
The exact path depends on the Office release and installation technology. A 32-bit Office installation can legitimately use 32-bit files on 64-bit Windows. Do not assume that a file belongs in C:WindowsSystem32 or C:WindowsSysWOW64.

Historical Office releases may contain different builds and architectures. Public file records are not a complete Microsoft version catalog, so there is no single version or path that every installation must have.
What the error messages mean
Windows may display messages such as:
- “The program can’t start because msoxev.dll is missing from your computer.”
- “The code execution cannot proceed because msoxev.dll was not found.”
- “There was a problem starting msoxev.dll. The specified module could not be found.”
- “Error loading msoxev.dll.”
- “msoxev.dll is either not designed to run on Windows or it contains an error.”
- “Cannot register msoxev.dll.”
These are Windows loader-style messages commonly associated with this file. They do not all indicate the same failure.
“Missing” or “not found”
The file may have been removed, quarantined, or never installed. Office may also be looking in the wrong installation because an older Office version was removed or the Office architecture changed.
“Specified module could not be found”
This wording can mean that a dependency required by msoxev.dll is missing. The named DLL may be present while another Office or system component cannot be loaded.

The file may be damaged, incompatible with the invoking Office installation, or replaced with a file from an incorrect release or architecture. A Microsoft signature supports the authenticity of a particular copy, but it does not prove that the file is correctly installed or compatible with the program using it.
Fix 1: Repair Microsoft Office
This is the best first step when the error appears while starting InfoPath, opening an InfoPath form, or using an Office feature.
Repair Click-to-Run Office
- Close all Office programs.
- Open Settings.
- Select Apps.
- Select Installed apps.
- Find your Microsoft Office or Microsoft 365 installation.
- Select the three-dot menu beside it.
- Choose Modify.
- Approve the administrator prompt if Windows displays one.
- Choose Online Repair.
- Select Repair.
- Follow the prompts and restart Windows when requested.
Online Repair is more comprehensive than Quick Repair because it can replace damaged or missing Office files. Quick Repair is faster and may be useful when the problem is minor, but use Online Repair when msoxev.dll is missing or corrupted.
After restarting, open InfoPath or the Office program that produced the error. If it starts without the message, the repair restored the shared Office component.
If Modify is unavailable, the installation may be managed by your organization, installed through an MSI-based Office edition, or already damaged enough that Windows cannot launch its maintenance process.

Repair an MSI-based Office installation
Some older Office editions use Windows Installer rather than Click-to-Run.
- Press Windows key + R.
- Type:
appwiz.cpl
- Press Enter.
- Select the Microsoft Office entry.
- Select Change.
- Choose Repair in the maintenance dialog.
- Complete the wizard.
- Restart Windows.
The labels vary between Office releases. Choose the repair option rather than removing the product unless repair has failed.
Check that you repaired the correct Office product
Multiple Office versions can coexist. If the failing application belongs to an older Office installation, repairing a newer Microsoft 365 installation may not change the files it uses.
Look at the full path shown in the error, if one is provided. Also check Settings > Apps > Installed apps for more than one Office entry. Repair the product associated with the failing InfoPath installation.
Fix 2: Reinstall the correct InfoPath or Office edition
Repair cannot restore a component if InfoPath was removed or the Office installation no longer contains the feature.
Microsoft provides an official InfoPath 2013 download page with separate x86 and x64 installers. The page states that an active Office 365 ProPlus subscription is required. Use the official InfoPath 2013 download page rather than a DLL download site.
Before installing, determine which architecture the existing Office deployment uses:
Free tools Windows power users keep installed
One-click scans. No signup required.
- Open an Office application that still works.
- Select File.
- Select Account.
- Select About the application.
- Read whether it says 32-bit or 64-bit.
If no Office application opens, check the installed product details in Settings > Apps > Installed apps or ask your organization’s administrator.
Install the matching architecture where possible. Do not mix a 32-bit InfoPath installer with a 64-bit Office deployment, or the reverse, without confirming that the combination is supported. A 32-bit Office installation on 64-bit Windows is normal, but its Office components must match the installation that invokes them.

After reinstalling:
- Restart Windows.
- Open Installed apps and confirm that the expected Office or InfoPath product appears.
- Start InfoPath or the affected Office program.
- Install updates through the supported Office servicing method.
MSI-based Office and Click-to-Run Office use different update and repair paths. Microsoft’s InfoPath 2013 update guidance explains this distinction. Microsoft also provides separate x86 and x64 update packages, including the InfoPath 2013 x64 update download.
InfoPath 2013 reached the end of its support lifecycle on July 14, 2026. As a result, reinstalling it may depend on your license, installation media, organizational policy, and whether the required package remains available to you.

Antivirus software can remove or quarantine an Office file. Do not immediately disable antivirus or replace the file manually.
- Open Windows Security from the Start menu.
- Select Virus & threat protection.
- Select Protection history.
- Review recent detections.
- Look for an event involving
msoxev.dllor the Office installation directory. - Expand the event and review the detected path and reason.
Only restore a file when all of the following are true:
- The path belongs to the expected Office installation.
- The file is part of a licensed Office or InfoPath installation.
- Its Microsoft signature can be verified.
- You have determined that the detection is a false positive.
If the file was quarantined from an unexpected directory, do not restore it. Run a full Microsoft Defender scan and repair or reinstall Office instead.
Protection History retains events for only a limited period, so an older quarantine may no longer be visible. Microsoft explains the available actions in its guide to Protection history in Windows Security.
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 minuteRestoring a quarantined file can cause Defender to detect it again. That does not by itself prove that the detection is wrong. If the file keeps disappearing after repair, contact your security administrator or reinstall Office from an official source.
Fix 4: Repair Windows components with DISM and SFC
DISM and SFC repair Windows components. They do not normally recreate an Office-owned msoxev.dll, so use them when the problem affects several programs, Windows servicing appears damaged, or Office repair reports broader system errors.
Run DISM first
- Open the Start menu.
- Type Command Prompt.
- Select Run as administrator.
- Select Yes at the User Account Control prompt.
- Run:
DISM /Online /Cleanup-Image /RestoreHealth
- Wait for the command to finish.
- Keep the window open even if progress appears paused.
When DISM completes successfully, run System File Checker:

sfc /scannow
Wait until verification reaches 100 percent. Restart Windows and test the affected Office application.
Possible SFC results include:
- Windows Resource Protection did not find any integrity violations: Windows system files were not damaged.
- Windows Resource Protection found corrupt files and successfully repaired them: restart and test again.
- Windows Resource Protection found corrupt files but was unable to fix some of them: run DISM again, restart, and repeat SFC. If the problem remains, continue with Office repair rather than copying a DLL.
Microsoft documents these commands in its System File Checker guidance.
Running these commands repeatedly will not replace a deliberately removed InfoPath component. If only InfoPath fails, Office repair or reinstall remains the relevant fix.
When you are hunting through component stores and repeating DISM and SFC without knowing which package is damaged, Outbyte PC Repair can scan for issues and show what it found; repairs are performed by the full version, but it is not required and Office reinstall remains the definitive fix for this Office-specific file.
Fix 5: Use System Restore after a clearly timed change
System Restore is appropriate when the error began immediately after a driver installation, update, cleanup operation, or other system change and a suitable restore point exists.
- Press Windows key + R.
- Type:
rstrui.exe
- Press Enter.
- Select Next.
- Choose a restore point created before the error began.
- Select Scan for affected programs if available.
- Review the programs and drivers that will be changed.
- Select Next, then Finish.
- Allow Windows to restart.
System Restore rolls back system files, registry settings, and installed programs while preserving personal files. It does not guarantee that a removed Office product will return. If the failure continues, repair or reinstall the correct Office installation.
Fix 6: Do not use generic regsvr32 commands
At least one documented build of msoxev.dll exposes COM registration-related entry points, including DllRegisterServer and DllUnregisterServer. That makes regsvr32 technically relevant to a controlled Office deployment or diagnostic procedure.
It does not make this command a general repair:
regsvr32 msoxev.dll
Registration cannot supply a missing file, restore its dependencies, select the correct Office version, or make a 32-bit DLL compatible with a 64-bit process. Running the wrong regsvr32 executable can also create an architecture mismatch.
Do not:
- Copy
msoxev.dllintoC:WindowsSystem32. - Copy a 32-bit file into
C:WindowsSysWOW64. - Register a file downloaded from an unofficial DLL site.
- Register a file whose signature or path is suspicious.
- Use
regsvr32before repairing the Office installation.
If an Office administrator specifically instructs you to register the original file, use the full path supplied by that administrator and the registration procedure appropriate to the Office architecture. Otherwise, let Office repair restore the file and its registry configuration. Microsoft describes the tool’s purpose in its regsvr32 documentation.

Why random DLL downloads are unsafe
Downloading an isolated msoxev.dll from a random DLL website can introduce several problems:
Best Value
- Video Link to instructions and Free support VIA Amazon
- Great Support fast responce
- 15 plus years of experiance
- Key is included
- The file may contain malware or have been modified.
- It may belong to a different Office release.
- It may use the wrong architecture.
- It may require dependencies that are also missing.
- Its version may not match the Office installation.
- Copying it into a Windows folder can create new loading or security problems.
- It does not repair the Office registry, servicing records, or related files.
Use Office repair, a licensed Microsoft installation source, and Microsoft’s official update packages instead. A Microsoft signature is useful when evaluating a specific copy, but signature verification does not establish that the file is installed in the correct location.
Is Device Manager or Windows Features relevant
Usually not.
msoxev.dll belongs to Office InfoPath, not a hardware driver. Device Manager will not normally restore it. Windows Features also does not provide a standard feature that reinstalls this Office component.
Use Device Manager only if the same incident includes separate hardware failures, display problems, or device errors. Use Turn Windows features on or off only when a different application specifically identifies a Windows optional component as missing. Neither should replace Office repair for this error.
Recommended Free Tools
If a driver update or system change coincided with the failure, first use Office repair and System Restore. Avoid installing unrelated driver packages as a substitute for restoring InfoPath.
When several devices have stale or mismatched drivers and manually identifying each version is slowing the diagnosis, Outbyte Driver Updater can scan and identify driver updates; the driver installation is performed by the full version, and it is not required for an Office-only msoxev.dll problem.
How to verify the file and installation
If msoxev.dll is present, check it without moving or replacing it:
- Open File Explorer.
- Browse to the path shown in the error or Office installation directory.
- Right-click
msoxev.dll. - Select Properties.
- Open the Digital Signatures tab, if present.
- Select the Microsoft signature.
- Choose Details.
- Confirm that Windows reports a valid signature.
Also check whether the file is located beneath an expected Office directory. A copy in a temporary folder, a user profile download directory, or an unrelated application folder deserves further investigation.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
If the file is signed but the error continues, the Office installation may still be damaged, the wrong Office version may be launching, or a dependency may be missing. Repair the associated Office product rather than replacing the signed file.
If the error still returns
Collect these details before escalating the problem:
- The exact error text.
- The name of the program that fails.
- Your Windows version.
- The Office product and version.
- Whether Office is Click-to-Run or MSI-based.
- Whether Office is 32-bit or 64-bit.
- The full path of
msoxev.dll, if shown. - Whether InfoPath appears in Settings > Apps > Installed apps.
- Whether Windows Security quarantined the file.
- Whether repair restored the file temporarily.
- Any related entry in Event Viewer > Windows Logs > Application.
If the repaired file disappears again, check Protection history and the file path. If only one Windows account is affected, testing a new user profile can help separate a profile problem from an Office installation problem. If every account is affected, focus on Office repair, security software, and system servicing.
The practical objective is not to obtain a standalone DLL. It is to restore the licensed Office or InfoPath installation that owns msoxev.dll.
