Just spreading the word. If you get an error message when you activate the Calculations pane of a the Cube editor in BIDS for Analysis Services 2005 and get a message saying Unknown Error. Error in Application, did you just install Office 2007 Beta 2 TR?
If so, that's what's causing the problem. Here's a link to the solution. http://sqlug.be/forums/339/ShowThread.aspx#339.
Cost me a few days. Didn't make the link to the Office TR installation. It's possible that just copying the 2047 build files to the OLE DB folder might work, but I did the steps Frederick posted and it got me past the problem.
