Uninstall Adobe Premier Pro 1.5 From Vista I Have Installed Adobe Premier Pro 2 But It Won’t Let Me Play, And I Cannot Uninstall To Fix It.?

I have installed Adobe premier pro 2 but it won't let me play, and I cannot uninstall to fix it.? - uninstall adobe premier pro 1.5 from vista

I get an error message when you try and said that my registration is invalid, and I need to reinstall Adobe PP 2 Behind it lies on the loading screen that says I have the trial version before installing the full version to uninstall. When I try to uninstall it gives me the opportunity to repair or remove. When I try to delete them and go for about 30 seconds, then gives me an error message that he was interrupted "installation". When I try to repair it, then reinstalled, but I'm still the same problem.

All help to run or remove it?

Thanks
Randall
