Windows 7: Zone Alarm in registry interfering with installation

Trying to install Win 7, and all is well until it checks compatability, and it says I have to remove Zone Alarm.

I don't remember ever installing Zone Alarm on this computer. I couldn't find any signs of it anywhere on the hard drive. I searched all over the web for different file names I should search for, but there are none on this computer....except when I run regedit, and under Legacy Dsvatant, there are two instances of Zone Alarm but I can't delete them. It won't allow me to remove them.

Any ideas what I should do? Should I install Zone Alarm and then remove it? I've cleaned everything else out. Can't wait to get rid of Vista, and this is so frustrating.

Thanks. I appreciate any help. I've been trying all day.

Try backing up all your data, and doing a clean install.

Tried. It won't work because the program doesn't exist on my computer.

Any idea if Registry Mechanic might be what's causing the problem? I think that's put out now by the ZA people.

No clean install for me. I don't want to go that way. I backed up with NovaStor, but the Windows 7 Advisor tells me I have to buy the new update in order for it to work with 7. There's got to be a way to get rid of these two files.

I just removed all of Registry Mechanic. I'll see if that maybe makes a difference.

Have you tried using Easy Transfer?

Where would I transfer to?

another hard drive, if you have one. Anywhere with sufficient storage will work.

Maybe try installing it and then uninstalling to clean things up.

I do not know if this will work, so others please confirm/deny this. Is it possible that he could save his Easy Transfer file to his desktop, do a clean install over the current installation, and then retrieve his file from Windows.old? It sounds possible, but is it advisable?
