If you let the program install itself to the default Program Files folder it is going to continue to give you problems.
Create a "Games" folder on the C drive and move the entire Ubisoft? folder into the Games folder and the changes should stay.
The following is the Default location for IL-2 1946 so you will need to find the install location for the IL-2 Ultimate edition and make the changes accordingly.
The retail DVD version of IL-2 Sturmovik 1946 is v4.07m.
The game version may be found in the bottom left of the game startup screen.
The installation file path defaults to:
(32 bit systems):
C:\Program Files\Ubisoft\IL-2 Sturmovik 1946
(64 bit systems):
C:\Program Files (x86)\Ubisoft\IL-2 Sturmovik 1946
Installation Tip:
**Changing "Program Files" to "Games" when you are installing the sim will make the patching process have fewer problems on machines that are using any Windows operating systems after WinXP.
Modified Filepath: C:\Games\Ubisoft\IL-2 Sturmovik 1946
(Use the same modified filepath for both 32 and 64 bit versions.)
