Sony Sound Forge 7 won't open since Windows 10 upgrade

Tried to open my registered Sony Sound Forge 7 software program today and realized that since Windows 10 upgrade, like some other software programs affected, this one won't open.

(1) Tried some of the suggestions in regedit but didn't see all of the Sony entries listed in the steps

(2) Tried opening with "run as administrator" - didn't work.

Any suggestions?

 

Add app/program to 'Open with' apps list

Am I missing something? I just want to add a program to the list of files in the "Open with" list; in win XP and 7 it was just a matter of associating the file type with the program but in win 10 this doesn't seem possible. To make it clear I don't want
to change the default program just to add a program to the 'Open with' list for example .html .css .js files I am developing need to be opened with a browser as default or sometimes Dreamweaver ( which IS in the list ) but sometimes I want to open it with
my text editor since it is quicker to see the contents of the file but in order to do so I need to... right click the file > select open with > choose another app > select my editor from the list.

I used to right click > select open with > choose my editor. Since I do this many times it is a pain to have the extra step.

Win 7 and Win 10 on network

I have home network with separate modem, router, and WAP's. My Windows 7 computer does NOT list the Windows 10 computers on network computer list but the Windows 10 computers network list DO list the Windows 7 computer.

Turned off firewalls, gave permissions, shared drives. Nothing allows Win 7 computer to access the Win 10 computers.

Any suggestions for a fix?
