Resolution

Use Regsvr32.exe to re-register the failing COM component. Regsvr32.exe is a program that you can use to register dynamic-link libraries (DLLs) and ActiveX controls in the registry. For example, to manually register the Sample.dll file, type the following at the command prompt:

C:\Regsvr32.exe Sample.dll

NOTE: This command line assumes that Regsvr32.exe and Sample.dll are both in the root folder of drive C.

Regsvr32.exe has the following command line switches:

/u - Unregister server
/s - Silent; displays no message boxes
/c - Console output

Regsvr32.exe is contained in a self-extracting .exe file named Regsv32a.exe. This file is available for download from the Microsoft Download Center. Click the file name below to download the file:
