I just had my emachine blow up and had to replace it with a new HP Pavillion. I (involuntarily) went from the XP operating system to Windows 7. Now, I have software I can't run and some of it was very useful and not replaceable like my audio processing software Cakewalk Pyro. I have the disks to load it, but I just get error messages. I understand I can spend another $150 to "upgrade" the windows 7 home version to professional and that supposedly will enable me to create a "virtual" XP system that can run old software. I am not thrilled about dumping in even more money or making the OS any more complicated than it already is. I just got off the phone with microsoft "support" and they said that the problem was HP's fault which is quite a coincidence because about ten minutes before that HP support line said it was simply a software incompatibility which it obviously is. Anyway to run prior software without making this more complicated and expensive? I have the old hard drive as an external drive, I tried directly starting the apps but they don't run on the new OS.
