problem Unistall with CIU v2

[alucard1973]

Good evening,
I have a rather annoying problem with CIU CIU 2030 and 2036 which has the same problem for uninstall.
Here is my problem:

The normal uninstallation without a backup source in the game directory is normally except that not delete the game folder when it is empty (have can do something?)

The other problem is more annoying is that if the backup is in the game folder (eg bin / 3DMGAME), when I uninstall the game and he asks me if I want to delete the backup, I'm YES or NO to always remove everything that is in the game's source directory.
Do you have a solution please?

I try everything CIU 2030, 2035, 2036 and still the same problem

sorry for my English
