Uninstall/Install canceling issue

Damion Posts: 5 Just Starting Out

So I downloaded the new version of Hitfilm and it won't install. If 1st tried to uninstall the old version like the site suggests but it keeps saying "Account already exists" and cancels the uninstall. Then when I try to just install the new version. It says the same thing and cancels the install. I tried going to every directory on my computer to manually delete every iteration of it I can find but even with them all (that I can find) deleted, it still won't install or uninstall.
