I have been using Audio Cleaning Lab v 1.03 on XP for a few years with excellent results. I have now upgraded to Windows 7 and ACL won't work properly. is there a fix I can download?
Unfortunately no, the code line of the software you have was not meant to be run under a 64bit Windows 7 system. You will need to purchase the newest Audio Cleaning Lab (version 17).
You can download the trial first, and them try it before you buy it.
