Scott, Install them same way you did initially. I use Topaz, and I had to go to the Topaz website (my account) and download the files again. Then follow their installation process. Have your serial numbers handy, you will be prompted to enter that information after the re-install, and the first time you launch the program. I'm not familiar with how Nik/Google deploys their products. I think will be the same way. Good luck . . . bgs.
