Yes, unextract the LFS U .exe from the upgrade or install zip (that you should still have lying around somewhere - else get the smallest update from the liveforspeed website).

Edit: bah, thought this was the U8 thread. You can downgrade to an older version, say patch Q... but you won't be able to race online, and the cars will handle different. So, erm, anyone?

I think the latest version posted for download at the main site http://www.liveforspeed.net/?page=downloads is version U, so you should be able to download the latest version listed and use the LFS.exe from that.
