This posting is to inform you of a slight variation in which the update to SP1 must be run on a Vista machine. Most of the instructions in this post apply but there is one exception, you must run the updates as an administrator.
Issue: When updating to SP1 on a Vista machine, you get the following message: A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.
Note: This message does not occur when running the update to the Update Utility but rather occurs when running the actual update to SP1. If you are unclear of the two-part update procedure, see this post.
Solution: After the Update Utility has installed, select Start->All Programs->D-Tools->Check for Server Updates (if on your server) or Start->All Programs->D-Tools->Check for Updates if you are on a Client machine, right-click and choose “Run as administrator”.
