By Catalyst, do yo mean AMD Catalyst for your video card? The troubleshooter tool is most likely trying to repair drivers.
To make this simple, try this:
Use this official utility from AMD: http://sites.amd.com/us/game/downloads/Pages/catalyst-uninstall-utility.aspx.
Follow the prompt and remove all existing amd drivers. Your screen may flash. This is okay.
After uninstall is complete, install auto detect from http://support.amd.com/us/gpudownload/windows/Pages/auto_detect.aspx. This program will automatically detect your video card and download the appropriate drivers.
Catalyst troubleshooter will not reappear.
