Having used every operating system since MS-DOS, I fell in love with Windows 7, proclaiming it their best EVER. I'll keep digging for answers and post if I find something interesting.

I cannot guarantee that this is due to a failure with Win 10, but I've successfully installed these same discs on a Win 7 computer (and yes, before uninstalling I did un-register and delete the serial # on that computer.) To add to my suspicions that Win 10 (or some related drivers) may be the issue, I also could not install two other creative programs from Serif that - prior to this - I've never had a problem installing. I've made several attempts, but have had no luck. I can find and open Encoder, Bridge, Encore, etc. However, when I loaded the two discs with CS5, everything appears to be installed EXCEPT Premiere Pro. Overall, I like most of what I've seen so far of the Win 10 interface and functions (except Control Panel.) and it has no issue with games I've installed.

I've just been attempting to install The Premiere Pro CS5 package on a new laptop that has the Windows 10 trial version.
