Can I save and transfer my audition version 3.0.1 to my new computer?

Please read our FAQ  about this. By searching diligently, you may find links to the download and serial number you require, but we can't help officially, I'm afraid. But note carefully - your original version and serial number is unable to be authenticated at all - you might as well throw them away. No, you can't just copy it across, either - the installer puts loads of links and bits of code (dlls, for instance) into the registry and a few other places, and without all of these in place it simply won't work.
