YoWindow cannot run under Win10 x64: flash player related

[beb]

Windows 10 x64 1511 build 10586.164
YoWindow 4 build 74

Adobe Flash players installed:
21.0.0.213 (ppapi, npapi user controlled)
Shockwave Flash Object (IE addon, OS controlled) is active.

After reinstalling YoWindow the app can not run any more, reporting:
"To enjoy YoWindow you need to install Flash Player (for Internet Explorer) 10.2 or later.
Get Adobe Flash Player
Exit"

As you know since Win 8 and up to Win 10 Flash Player is integrated in IE and user can not install it manually.

So only "Exit" option available.

What to do?

Finally solution seemed to be found:
1. Uninstall Security update for Adobe Flash Player for Windows 10 Version 1511 (KB3144756, March 10, 2016)
2. Check updates, item above will be found and installed again.
3. Reboot.
4. YoWindow returns functional.

this fix did not work for me but rc b75 works fine with the flash update on April 12 2016
