Hi, I had to format my HDD where RC8 was installed. The drive came out formatting with another drive letter, which is fine. BUT now I can't reinstall RC8 as during the install routine I cannot choose the install directory anymore, and then gets some error message and the routine fails to install. I tried to uninstall with the help of application menu in W10 but of course I get a error message telling me the drive does not exist, which is correct as the drive has been formatted before RC8 could have been desinstalled. Now I guess I have to clean the registry to enable a fresh and clean reinstall of RC8, any advise what are the keys to clear ?
