Hi, this my first post. My Prevx license won't install. I put the license in, the pop-up box says it is activated, but it goes back to as it was. Now some background. When I installed Prevx, I turned off my Iobit 360 Security Pro because it uses too much CPU during installations. (I have now been told that Iobit has an install mode). Anyway, I have looked in the Prevx program files folder in Windows, and the only thing in there is Prevx, nothing else. Either it is very light/compact, or something fouled up. I mean, where could you even hold the license information in the folder? Also, I did one uninstall with Revo-uninstaller. (Windows never even picked it up in the add/remove programs from the control panel). Now Revo-uninstaller gives me an error message when I try to uninstall it. And in the "start-all programs" menu, there is no uninstaller. There seems to be nothing in this program. In my Process Explorer Prevx is running in two places. When I try a new install, Prevx just starts running, with no new installation screen, and no new files in the folder. Is the registry wrecked? Should I manually delete? Should I use CCleaner on the registry? Do I have to re-install Windows? This program looks good, and I want to try it; but if it does not work/install properly, there is no point. Thank you for your time, and please help. Jace.
