My Paint.net got accidently deleted under the program files but now I cant install newer versions as it cant uninstall the old version 3.22 because old configuration data is still in the pc somewhere. Can't even get latest beta to install on a seperate hard disk. Sometimes the installer asks for the installation disk or the location of a file that got deleted the first time round. Can this installer be altered to just reinstall even if the old installation was stuffed up?
