VSIP - package load failure

hi,
some times VSIP 8.0(VS SDK 2005) throws a package load failure even if the PLK got is proper.
the reason may be that there is a DLL which will be loaded by VSIP (may be in VSPKG.cpp class).
is that dll is not loadable , then Visual Studio throws this error.

solution : run regasm.exe on the dll (which has to be loaded by VSIP).

hope this helps people who want to develop new extensible stuff to VS 2005.
