Step 4: Re-register the regsvcs.exe File

Sometimes, regsvcs.exe itself might not be registered correctly with the system. You can manually re-register it.

Why this helps: Re-registering refreshes the system’s reference to the file, fixing errors caused by missing or broken registrations.

How to re-register:

  1. Open Command Prompt as administrator (see Step 2).
  2. Type the following command and press Enter:
regsvr32 %windir%Microsoft.NETFrameworkv4.0.30319regsvcs.exe

Note: Adjust the path if your system uses a different .NET Framework version.

Step 5: Check Permissions on regsvcs.exe

Incorrect permissions on the regsvcs.exe file can prevent it from running properly.

Why this helps: Ensuring the right permissions allows the system and applications to access and execute the file.

How to check permissions:

  1. Navigate to C:WindowsMicrosoft.NETFrameworkv4.0.30319 (or your correct framework folder).
  2. Right-click regsvcs.exe and select Properties.
  3. Go to the Security tab.
  4. Check that Administrators and System have Full control.
  5. If permissions are missing, click Edit to adjust them.

Step 6: Run the Application in Compatibility Mode

If regsvcs.exe errors occur when running specific programs, try running the app in compatibility mode.

Why this helps: Compatibility mode can resolve conflicts between older applications and Windows 11.

How to enable compatibility mode:

  1. Right-click the application executable (.exe) file.
  2. Select Properties.
  3. Go to the Compatibility tab.
  4. Check Run this program in compatibility mode for: and select an earlier version of Windows.
  5. Click Apply and then OK.

Step 7: Use the Deployment Image Servicing and Management (DISM) Tool

If SFC does not fix the problem, DISM can repair the Windows image, which may resolve deeper system issues.

Why this helps: DISM fixes corrupted system components that SFC cannot repair.

How to run DISM:

  1. Open Command Prompt as administrator.
  2. Type the following commands one by one, pressing Enter after each:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
