Make sure you have installed PJ64 via an installation pack rather than from a zipped PJ64 exe
Install the following runtime packages
https://www.microsoft.com/en-gb/down....aspx?id=40784
https://www.microsoft.com/en-gb/down...ils.aspx?id=29
https://www.microsoft.com/en-us/down...ils.aspx?id=35
Make sure you reboot your PC after installing those
Then try PJ64 again
If the error remains, uninstall PJ64 and use the installer from http://forum.pj64-emu.com/showpost.p...1&postcount=31 to re-install it
