Hey, i can't install glsetup for my savage4 !

Hi, everytime i run glsetup, it’ll stop at s3gamma.dll, saying the file’s corrupted.
What’s going on ? is there anyway for me to download this driver without using glsetup.exe ? can i download the files directly ?

seems like some files are corrupted in the server… i’ve tried again and again to download it, but to no avail, it’ll just say “An I/O error has occured while installing a file. this is normally caused by bad installation media or a corrupt installation file” the retry button don’t work, so i have to press the abort button…
is there anywhere else where i can get the files that i need ??
thanks for any help
