--- Comment #4 from Leonid Volnitsky leonid@volnitsky.com 2008-03-24 16:20:41 --- Yes, I did tried with new ~/.wine (mv .wine .wine.old and then new MS Office install).
There are actually two bugs, which can be related or not related and they could've been introduced in different wine versions.
First bug is with message "This application must be installed to run. ...". Second bug is that it is impossible to register installed newly MS Office. I will try to do regression test.
