Getting plextools update to work

i just recently bought a PX-716A off ebay for a real good price but noticed it doesn’t come with the plextools CD and i was wondering if their is a way to get the update download to work and install plextools?

akey in the registry seems the way to go.
i dont know this location because i have the cd

anybody now how to do this?

Yes but it’s not allowed to install PlexTools without the original install CD or without paying for it, so we can’t help you.
