In addition to the excellent post in the FAQ about this (http://www.adobeforums.com/cgi-bin/webx/.eed5198.3bc186bb), I found that on Microsoft Vista I have to run ach.exe in Windows XP SP2 compatibility mode and run it as an administrator. It seems ACH.EXE is attempting to write to the registry every launch, and Vista doesn’t prompt for elevation of privileges to admin mode. Not sure if it’s an RC2 bug in Vista or a bug in the way ach.exe was implemented, but in the meantime this is a workaround. Right-click on ach.exe and select properties to see the Compatibility tab and these settings.

This seems to be true for many programs which do not have MS accreditation. It is part of the advanced security features of Vista which prevents unauthorised programs from running.
However, although I had to turn on compatibility mode and check the ‘Run as Administrator’ check box the first time I ran the program, I have turned these off now and it runs just fine.
