Hey, [@Dee], try right-clickign on the installer and selecting [ Run as Administrator ].
__________
Or … try rebooting into [ Safe mode with networking ] to install it, you may have something watching and blocking, safe mode turn off all that other stuff.
Web search [ how to start in safe mode for windows ( your version, XP, 7, 8, 8,1, 10 ) ].
If that works, then something in regular / virtual / non safe ( ! ) mode is blocking the ports Audials needs.
Let us know ow it goes.
