What has always puzzled me about Parallels users (of which I was one) is, why not just use Boot Camp Assistant and boot from Windoze, instead of running it and your Mac stuff at half-speed on an emulator? You have it right now on your Mac (in Utilities) and you can set it up in a few minutes. There's no way to point it elsewhere, especially on what amounts to a different 'computer' with a completely different OS. The problem with either approach is, a Mac Steinberg app (or any app) is programmed to look for the license validation in one specific location on your Mac's system. In theory, you could run the Windoze version of eLicenser that way. On the other hand, there's Wine, which runs Windoze apps inside a shell. You can transfer files between the two systems (if memory serves) and even have Parallels use your Mac's hardware, but it's more or less two completely different systems using one machine simultaneously. Parallels actually creates a virtual Windoze hard drive inside of your Mac's drive.
