What do I do if fastProject crashes after installing or crashes randomly?
If you have the correct version of fastProject for your version Microsoft Project (32-bit/64-bit), and you have all the latest updates of Microsoft Project, then it's quite possible fastProject has got corrupted. This primarily happens with Microsoft Project 2013.
To fix this problem:
Navigate to c:\Program Files\fastProject (or for 64-bit Windows c:\Program Files (x86)\fastProject)
Double click on the file Global.mpt
A number of messages will appear. Ignore them by simply clicking OK, etc.
When the messages stop, exit Microsoft Project
Start fastProject again
fastProject should now open and register correctly.
