Thanks man!
I know it's a bug in space indicators, but I don't know what are you trying to say... In your PC it says 10700GB? Because I get 10.7GB. And my problem is that I have under 1gig free space on C: and it displays something like 638GB instead of MB, and I really didn't spent time fixing that. Btw, I only modified the original posted script.
And another thing, during installation the orig script displays remaining time, but I only get something in russian instead of the actual time (searched the entire script and I don't think I've missed a translation), so I disabled it entirely.
