Hi Devashish,

Thanks for posting on this forum.

Based on your description, it seems that you need to know whether .net 4.0 is compatible with Office 2000 PIA or not.

Since the Office 2000 is expired at 2009/7/14: http://support.microsoft.com/lifecycle/?p1=2484 And .net 4.0 release at 2011, so there is no system test they are compatible or not.

And I suggest you don't try office 2000 PIA on .net 4.0FM. For the requirements on office 2000, you can try .net fm 1.1.

I hope this will be helpful.

Best regards,

Hi Devashish,

For the first one,

>>1) interop.shdocvw.dll (Version=1.1.0.0)

>>2) interop.scripting.dll (Version=1.0.0.0)

Actually, these two dll is interop dll, they are wrapped from shdocvw.dll and scripting.dll. You can try to directly add the two references to into your .net 4.0 project, and VS will generate the related interop assemblies. So you don't need to suffer from this kind of issues.

>>3) VBIDE.dll (Version=5.3.0.0)

This dll is used by VS, in your newly development, this dll should not be used.

>>4) Microsoft.mshtml.dll (Version=7.0.3300.0)

Yes.

Best regards,
