Dave, I followed your suggestion but still get the same error. While testing, I did find that if the Global Profile document is open, I can open the My Activities page from the bookmark. If I close the Global Profile document, I begin getting the "isn't installed" message again.
Cheers
Manuel
I just tested again, and noticed that as long as there is a document open from any VIC database, the My Activities page can be launched from the bookmark toolbar. Closing the documents produces the error message again.
