I recently upgraded from P3Dv3 to P3Dv4. As part of my transfer I uninstalled every P3D related software I had installed then formatted the drive I use exclusively for P3D. I am now unable to install any FSDT product. The installer will hang on the "Registering Files" part of the installer. I'm thinking I still have some files relating to the old installation floating around somewhere, but I'm not sure where to look. Any ideas?
