In the Control panel -> Add or remove programs
Thanks for the quick replies to my seemingly stupid question... But, in Vista 'Add / Remove Programs' is called 'Programs and Features', and - as I stated in my question - there the Engineer's Toolset is not listed.
Greg hinted to re-run the Setup program, in order to remove the software. I will try that and let you know, OK?
Rene - there should be an entry in the add / remove programs / features section of the control panel. If not, you can re-run the installer, then select the remove option.
There was no entry in the Programs & Features section of the Control Panel. Also, the Installer does not have a Remove option. But after installing the software for the second time, it created the desired entry in Programs & Featues.
So, I think something went wrong registering the software correctly at the first install. Currently, my machine is uninstalling the Toolset.
Thanks for the help!
