How to unregister a dll?

[Sumeetha]

Hi,

If i give
regsvr32 /u "C:\Program Files\Microsoft Office\Office\MSO9.DLL"

It pops up this err msg
C:\Program Files\Microsoft Office\Office\MSO9.DLL was loaded, but the DllUnregisterServer entry point was not found.

DllUnregisterServer may not be exported, or a corrupt version of C:\Program Files\Microsoft Office\Office\MSO9.DLL may be in memory. Consider using PView to detect and remove it.

How do i register and unregister DLLs?

Well that is how you would go about doing it. Try what the message code says and use pview.exe or tlist.exe or some of the process viewer apps from www.sysinternals.com and see who has MSO9.DLL loaded in thier process space. Stop those processes and try and unregister again.

of course MS09.dll has to have entry points like:
DllUnregisterServer()
DllRegisterServer()
