PakeKeeper Pro is not compatible with Windows 7. This application was developed only for Windows NT, 98, 2000, ME, 95, Mac, Linux and Unix. You can try to install a virtual machine in Windows 7 with the help of VirtualBox but that does not guarantee that it will work. The recommended OS for the VirtualBox is Windows XP. After the Windows XP has been installed in the virtual machine, transfer the application and run it in compatibility mode.
