Can't Reinstall Norton Ghost On Windows 7

I had some kind of problem with my Ghost 15 installation. I kept giving me this message that it couldn't communicate with my computer? Probably had something to do with getting a new external hard drive for my backlups.

I finally decided to just reinstall it, to reset everything. It told me that I had to uninstall it first. I did that and it still kept telling my I had to uninstall.

I ran Revo Uninstaller. It still kept telling me I had to uninstall it before I could reinstall it.

I finally found the Norton Removal Tool and after running that it would let my reinstall.

When I started it, it said I didn't have permission to run it, even when I logged in as Administrator. I found the instructions that said I had to uninstall it again, run the reset permissions tool, and then reinstall it again.

I think I did that, (it's weird takes me to a page with no active buttons and I have to click at the top of the screen giving permission to install something, then nothing) now it still tells me that I don't have permission to configure Ghost when I start it.

I'm about ready to give up and switch to another program, I've run Ghost for years, but this is crazy. I'm running Windows 7 Home Premium, I have the UAC turned off, I don't know what else I can do.
