I have the full registered version of RegDefend installed, but wanted to try AppDefend before buying a licence for that. Having shut down RegDefend by clicking on 'Exit' on the taskbar icon, I attempted to install what I then saw was the beta version of AppDefend, there seemingly being no final version of that software. The installation failed as a certain entry could not be made to the Registry. I then had to use a registry cleaner (RegVac) as RegDefend had reverted to an earlier trial version when AppDefend was performing a rollback. I could not find any guidance on this problem, so e-mailed Support at Ghost Security, wihout any response thus far.
