Hi,
do all your installers use DISK C as temporary drive? I don't have enough free space on this drive to install "flatout" how can i make your installer use another drive when decompressing files?
Thx for help in advance

When you use the installer, it has a grey button marked "options" which has an option to change where the game will be installed to.

As Flatout is only 900Mb, if you don't have enough free space on your C drive, I strongly suggest that you make some space on it (erase unnecessary files and apps, use CCleaner to clean all the caches and temp files...).
I don't say that for you to install Flatout on C drive, just because an actual operating system need several Gb on its main disk to run correctly. If Flatout uses all your free space, it may means that you have 1Gb or less on your C drive, and that's not big.
Hope it can help ;)

It is common for any type of installer to use the system designated "temp" folder for temporary files. This will be located in your user directory, which is most often on drive C.
You should always make sure you have a good amount of free space on the drive that contains the temp folder. If that is impossible or impractical, your best alternative may be to change your system settings to use a temp folder on a different drive with more space.

Wow. Less than a gig of free space on your C: drive? Like others have said, it is well past time for some house cleaning, your OS will thank you.

i remember having same problem when my system hd was only 5 GB, and needed tu burn something, or instal demo that had to first extract to "temp" folder which is on system disc.

Usually some trash at %temp% ;)
(to use that, just go on startmenu, to RUN and enter it)
So many programs dont clean up the temp folder when they close.. so sad, that programs litter computers whit trash bytes. ;)

HDDs are dirt cheap these days. Sounds like it's time to stick another one into your system.

thx everyone for help. I wasn't installing flatout on C, i wanted to install it on another partition where there is place for 100 flatout installs :). But the installer just didn't run and show only lack of space on C hard drive. I just resized my partiion and everything is ok now.
Another solution to this problem is (as i was told by support staff) to change envirenmental variables TEMP and TMP to a location on another partition, where there's enough place for temp files.
