It functions under Vista and registration does NOT need an email address, just pasting in the key and registering is sufficient. If you want to put this onto a drive other than C: userappdata the hard coded default install location of softorbits programs use innoextractor to extract the installer contents and manually move the extracted contents to where you want/need them to be and create shortcuts as necessary. I cannot test it to see how well it repairs broken JPG or PSD files as I don’t have any broken ones oddly enough but if that rare occurrence happens I’ll give it a try.
