Solution 1

It looks like whichever program or process you're trying to initialize either isn't installed on your machine, has a damaged installation or needs to be registered.
Either install it, repair it (via Add/Remove Programs) or register it (via regsrv32.exe).

You should resister your MSFlexGridLib comm control
because it may damage or corrupted

Solution 3

I think you are trying to reference the old .NET 1.1 interop DLLs. Try removing those references and re-add the COM reference, which will automatically create the .NET 2.0 interop shim DLLs for you.

I'v suggested what you can do. Have you given that a try?

shanavas_sm 23-Apr-11 11:24am

yes iam trying to refer 1.1 interop dlls.but these MSFlexgrid dll are not available with me

Nish Nishant 23-Apr-11 11:25am

You need the original COM DLL to be able to resolve this. The 1.1 interop DLLs will not work any more.
