Problem is caused when you run Report Builder from multiple SharePoint servers. RB is cached with setting from previous server and cannot run with this settings on new one.
- Open a command prompt (Run as admin).
- Enter the following: rundll32 dfshim CleanOnlineAppCache
- Press Enter.
Sometimes, you have to do additional operations:
- Restart browser
- Go to the C:\Users\[User Name]\AppData\Local\Apps\2.0 and delete the all temporary files.
