Uninstalling a project is greatly assisted by the project's folder organization.
There is a project folder and all of the project's folders and files are children of the project folder. So located the project folder and delete it -- the entire project is now uninstalled.
Ease of removal results from the fact that the tools do not use any dynamic link libraries (dll's) or other required binary, image or miscellaneous files.
Instead, each ModelTools tool is a totally selt-contained executable file. Locate the executable file (the tool name with an .exe filename extension). Locate the file and delete it.
ModelTools tools do use the Windows operating system registry, so in addition to deleting the tool executable there is some required registry cleanup (detailed next).
