Check your MindManager update, via the Tools menu/Ribbon. (click
here to see the latest Mindjet update information).
Unfortunately, the TPAssist installer sacrifices functionality for speed and
assumes "MindManager.EXE" is located in C:\Program Files. If you have installed
MindManager to another location, like the D: drive, you need to fool the
TPAssist installer, by copying MindManager.EXE to C:\Program Files folder. You
can delete this file after installing TPAssist.
