Installed Demo and now can't install

Avast Business Avast Server Protection

I downloaded the trial version and we loved it. I ordered the full version and uninstalled the Demo (I’m guessing this was bad) and Now I can’t re-install with the full version. When I runn the install .exe, it does nothing. Is there a reg key I need to delete or another way to re-install? I have the key ready but I can’t get to that point.
Thanks!

Looks like the answer was here.

I’ll give it a try

You just need to add the new (bought) key and the trial will become pro version.

Or you can make an installation from the scratch:

  1. Uninstall avast from Control Panel first.
  2. Boot.
  3. Download the latest version of Avast Uninstall and use it for complete uninstallation.
  4. Boot.
  5. Install again the latest avast! version.
  6. Boot.
  7. Check and post the results.

Thanks. Just removing the above reg key took care of it.
