well i got it to work with this way
Code:
UninstallDisplaySize= 2147483648
and got it to work like that too
Code:
ExtraDiskSpaceRequired= 2147483648
and those two displays 2GB, and i could make it more than that aswell, since u couldn't make it automatically calculated so i had to manually add the size in bytes so i guess the case is solved atm
thanks bro for your time and effort in trying to help me ..
as i said the issue is in the calculations itself.
