> what is the closest version to 12.41 where coolbits worked so i can copy the dll files from it?
12.40 coolbits worked for me, so that'd be the closest version. If I'm not mistaken, the WHQL's usually have coolbits disabled, which 12.41 is basically just the WHQL version of the 12.40's. Just to let you know, the 12.60's are much, much faster (for me at least) and coolbits also works for them.
