Fix Serious System Problems Caused by the Wrong Version of a DLL File

If you see an error message stating that the wrong version of a particular DLL file is installed on your system, you can solve the problem by copying an updated version of the DLL file in place of the version on your PC. However doing this may not itself stop the error message ? Windows may still report it has the wrong version of the file. If this is the case then it is likely that the old version of the DLL is still in memory and you need to register the new file with the system.

You can do this by clicking Start > Run, typing regsvr32 /i dll-name and clicking OK, where dll-name is the full name and path of the dll file that you want to register. You can also register DLL files by dragging and dropping the DLL file onto the regsvr32 program, located in the C:\Windows\System32.
