I can confirm, this worked for me.
Go to your "User Account Settings" (type "User Accounts" into start) and create new user with administrative rights. Also create password for this new account (I called mine GalCiv). Click on start, on arrow next to "Shut down" and click "Switch user". Log into this new account. Now you need to find GalCiv.exe, it will most probably be in "C:\Program Files (x86)\Steam\SteamApps\common\Galactic Civilizations III\GalCiv3.exe" run it, wait for game to load menu ... now you should see menu as it should be (if not restart PC and try running the game from new account again).
Afterwards log out of this account and log in back to your normal account. Now find the GalCiv.exe file again and create shortcut on desktop (delete steam created shortcut from desktop). Now right click on your newly created shortcut and click properties. Now we need to make this shortcut use the newly created account to run the game.
Paste this into target field in front of current text:
- C:\Windows\System32\runas.exe /user:GalCiv /savecred
(GalCiv is the name of newly created account, yours can be named differently, use name of your new account)
so the target field looks something like this:
- C:\Windows\System32\runas.exe /user:GalCiv /savecred "C:\Program Files (x86)\Steam\SteamApps\common\Galactic Civilizations III\GalCiv3.exe"
click on OK (icon will change to generic one, you can change it back to galciv's icon by clicking on change icon in properties) and doubleclick on this new shortcut, DOS window will open asking you for password of newly created account (you need to type it only once)
And now, enjoy the game
I hope this will help someone
BIG FAT WARNING: If you restart/turn off your PC, you will need to log into new account and run GalCiv once to have menus ok in normal account.
