I can only get my original version of mvp 2005 to run under Windows 8.1 Update 1.. if i try the mvp12 or mvp13 mods it will tank..
Although interestingly, it seems if i first reboot the machine, then launch it, it works.. but if i later close it and reopen it will not.
The exact same MVP12/13 install will work fine under a Windows 7 x64 install.
The crash occurs after choosing the quick game then "GO" .. progress bar 50% then crash.. mvp2005.exe has stopped working.
At first I thought maybe it was the newer nvidia driver causing the issue, but then i installed the 11/2013 driver (which works under Windows 8.0 btw, reboot or not).. and this didnt help, so I believe it is specific to 8.1 or 8.1 with update 1.
