For some reason I can not add reference to MS Word file MSWORD.OLB. It should be (and file is) located in:
c:\Program Files\Common Files\microsoft shared\OFFICE11\
I guess that problem is in Windows 7, since with XP I did not had same problem. Of course, Office is installed on machine.
Also, I noticed that Path in Reference properties is empty… Can I fill it somehow manually, to avoid this problem, or there is some other solution?
One should install the primary office interops and reference those, not the actual programs.:
Microsoft Office 2010: Primary Interop Assemblies Redistributable
2007 Microsoft Office System Update: Redistributable Primary Interop Assemblies
