Customizing the InstallPath and Foldername location doesn't work in 7.3 if you were using my 7.2 custom.ini config and they'll only break the non-folder shortcuts which is a nuisance. Otherwise you're doing something wrong. Also adding this line to the pdvd7.reg file stops the registration dialog box ever popping up, well it hasn't yet.
