Is this some component which you copied and added a reference to in your project?

You might need to register this with windows.

Go to the directory where you have the DLL file (call it someCOMcomponen t.dll)
c:\Windows\Syst em32\regsrv32 someCOMcomponen t.dll

this will register the dll, and hopefully you should not get that error

I have no idea about this component.I did no copy or add it.Also i am not finding the path c:\Windows\Syst em32\regsrv32.I have WINXP so i tried c:\\WINXP. But i cannot find c:\\WINXP\Syste m32 .Any other suggestion on what the problem is?
