Ms Office crash then any File dialog window appears (Open/Save file, add/save attachment and so on))

Couple week ago I faced with the problem that any MS office app - Word, Outlook, Excel, Power Point hangs when any of File Dialogs appears.


Finally I solved my problem:
Issue is connected to the non accessible network drive case and in my case caused by
the BizTalk BTSAsmExt.dll COM component which creates kind of system folder/drive for only bizTalk DLLs in GAC

BizTalk Assembly Viewer component:

Looks like feature is not compartible with MS Office :)

In order to uninstall it just run something like:

regsvr32 /u BTSAsmExt.dll

Or read more detailed instructions here:

Now I can enjoy  Open/Save File feature of MS Office package
