When I got it to work I had already backed up my data using Acronis to an external drive, so I skipped the "Easy Transfer" steps to backup my data in Step 1. So I guess I went with the default process without the backup. If you are going to try again, try having the Vista version of the OpticalDrive PM already on your machine when you run the upgrade. When you do run it be sure to set it to run in Vista SP2 mode. You might also check all of the registry entries again to make sure you modify those. When I first opened the registry to the point indicated, there was no data until I clicked on the register again, then I could make the changes. Once the Vista version is installed, run step 3 and then check your registry entries to make sure they are fixed or missing. Good luck hope you succeed this time!
