We're running SQL 2005 on Win2K3 server and are using SSRS. Here's the situation:

1. I can run Report Builder from localhost
2. My coworker can run Report Builder on his Vista computer
3. Another coworker can run Report Builder on his XP SP3 computer (IE7)
4. I can NOT run Report Builder on my XP SP3 computer (IE7)

I'm told that it could be anything from an errant registry entry to a group policy problem. Here is what I've tried:

• Put the site into "Trusted Sites" with "low" security
• re-install .NET
• create a new local user account and attempt to run it

The results? Every single time, I get a dialog box: "Application cannot be started. Contact the application vendor"

I click the details button and get this:

I'm really at a loss. I'm certain there is something on my PC preventing the application from running - but I just don't know what. Google hasn't been much of a help because most problems are related to the server configuration (which I know is correct since it works on other PCs)

Help me, Overflow Kenobi, you're my only hope..
