Q108188: Incompatible Version of the RPC Stub
Problem
You may see the following error:



More Information
This error is caused by an incompatible version of a DLL that was installed on the system, such as Oleaut32.dll, Olepro32.dll, Asycfilt.dll, or Stdole2.tlb. For example, version 3.50 of Oleaut32.dll is installed and used only by Windows XP, and so causes this error if it is installed on a machine running any other operating system.
Fix

Following are three possible resolutions for this error. Choose the appropriate method for your computer.

Microsoft Office 2000 or an Office 2000 Component IS Installed on Your Computer

If you have Microsoft Office or an Office 2000 component installed, install the Office 2000 Service Release 1. You can use this solution for any operating system.

For information on what an Office 2000 Component is, refer to the related topics section of this article.

Microsoft Office 2000 or an Office 2000 Component IS NOT Installed on Your Computer

If you do not have Office 2000 or an Office 2000 component installed on your computer, download and install the mcrepair.exe tool. When it prompts you to overwrite newer files, make sure you click YES for each file. You can use this solution for any operating system.

You Are Using Windows 98 or 95

On Windows 98 and 95, this error may be caused by a bad version of oleaut32.dll. To correct this problem, follow these directions to remove the old file and reinstall it.

Warning: This resolution requires you to modify your system folder. Modifications to the Windows system, if not done correctly, can cause serious problems to your system.

  1. Download to your desktop, but do not run, the Distributed Component Object Model (DCOM) file appropriate for your system.
  2. Select start > shutdown.
  3. Select restart in MS-DOS mode.
  4. At the command prompt c:\WINDOWS, enter the following commands on separate lines as shown. Windows automatically restarts.

    CD c:\windows\system
    rename oleaut32.dll oleaut32.old
    exit

  5. Ignore the error message: "A required .DLL file, C:\windows\system\oleaut32.dll, was not found." This error message appears because the file was renamed in step 4.
  6. Log in as normal.
  7. Double-click the file you downloaded to your desktop in step 1. Click yes to the dialog that opens. The dcom.exe file installs a new oleaut32.dll file.
  8. After DCOM has been installed, select start > restart.

If your computer fails to function properly after following the above instructions, you can restore your original oleaut32.dll file by doing the following:

  1. Select start > shutdown.
  2. Select restart in MS-DOS mode.
  3. At the command prompt c:\WINDOWS, enter the following commands on separate lines as shown. This restores the old oleaut32.dll file.

    CD c:\windows\system
    rename oleaut32.old oleaut32.dll
    exit

  4. Windows automatically restarts. If it does not, select start > restart.
