cameraraw6-7_r1_win_030612 won't install on my Win7x64 machine
I extracted the zip to a folder on my desktop, selected & doulble cliked AdobePatchInstaller, selected "RUN" and I get "error loading updater workflow"
Did I get the wrong thing? Is there a 64 bit only version?
Sounds like you got the right thing. I've been able to install it no problem on my Windows 7 x64 system.
Try running AdobePatchInstaller.exe using the right mouse button and choosing Run As Administrator.
