Flash Player issue

I'm hoping there's some Flash Player guru somewhere that can help me solve the problem I've been having since Windows 7 and/or Flash Player 11.

I have a program that uses "flash.ocx" and every time Flash Player (?) gets updated, this program fails to perform properly. I have to replace the updated "flash.ocx" with release 11, then the program works OK.

The program is Samsung New PC Studio, and it allows me to manage all the stuff in my Samsung cell phone using my computer.  This program worked fine in Windows 7 but not Windows 8, 8.1, or 10.  I"m on Windows 10 now and as I said, I have to keep back-leveling flash.ocx to the old release 11 version.  Specifically file version 11.9.900.170.

New PC Studio fails to detect my cell phone even though Windows can see it.  If I try to sync files between the computer and the phone the program tells me no phone is connected. The program also fails to show the phone icon on the screen.

As soon as I replace flash.ocx (currently at release 20) with the old release 11 version, the program detects the phone and shows the phone icon on its screen and I am then able to transfer any and all files back and forth between the computer and the phone.

I have also reported this problem to the Samsung folks.  Hopefully someone somewhere can shed some light on this issue.
