Reading through this thread it seems some have already tried to help with your issue. So I say this - if
you see the program in "Programs and Features" uninstall it. If you do not see it, it is not installed!!!
Either way - go here Tinker
and "Download" Games For Windows Live" (GFWL) Then install Tinker. Note that you will need GFWL up and running, plus a GFWL account to be able to install and play the game. - follow the instructions.
If the program (Tinker) is properly
installed, the only
files in the folder should be these...
And the folder will be located in either...
C:\Program Files (x86)\Microsoft Games\Tinker -(64-bit)
C:\Program Files\Microsoft Games\Tinker - (32-bit)
This is the "Official" microsoft way to get Tinker. If you're still having problems, than I have no other solution at this time.
