--- Comment #18 from Anastasius Focht focht@gmx.net --- Hello,
--- quote --- Is there a way to do a pre/post installation diff under Windows as to find out exactly what the installer did to the system? --- quote ---
there are certainly snapshot/monitor tools for Windows that hook into the system to record filesystem and registry changes during software installation:

There are gazillion information resources about this topic ... Google is your friend.
--- quote --- Under wine we would simply copy the wineprefix directory as a baseline and then run a post installation wineprefix diff. --- quote ---
While this is certainly doable, be aware there is no support for bugs reported with these "manual fixup" installations ('winetricks' being the exception). Bug reports without proper installer run (msi, installshield, ...) will be usually rejected/ignored.
