Cant uninstall TP?

This is what I get

Error in Package Installation
At least one error was encountered during a test installation of this package. It is strongly recommended that you do not continue with installation unless you know what you are doing, and have made a backup very recently. This error may be caused by a conflict between the package you're trying to install and another package you have already installed, an error in the package, a package which requires another package that you don't have installed yet, or a package designed for another version of SMF.

To uninstall TP just replace the very same files TP changes during the install with fresh files from the SMF package.
Then (if you dont want to save any content at all from TP ) you remove the TP tables from the database manually through phpmyadmin

The files TP changes during the install you can see on the modification document here
