Flash 20.0.0.228 inside MFC C++ is now showing as blank screen

Question

Hi,Recent update to Flash v.20.0.0.228 (ActiveX) used in C++ Application that was working until this update is not working anymore, now is just showing a blank screen. Debugging the app didn't throw any error in any case (with all exceptions turned on in MS VS). This is happening in all calls to .swf with all our applications (200+) in all clients (a lot) that ran the update.Tested in several machines with Windows 7 to 10, new update 100% fails and old one 100% success. Seems nothing to do with SO.Example:Rolling back to flash v. 19.0.0.245, it runs correctly:Thanks in advance,Carlos

Carlos, I filed the bug:Bug#4101067 - Unable to play local swf files in Flash Player 20 using 'file' protocol

*to upper replies: Thank you, but don't think its the same issue here. And i think its fairly easy for you to reproduce now we managed ourselfs to get where the problem is and get it working with a workaround.

We did a rollback in our code and detected that if we rollback a patch applied to secure the policies enforced some versions ago (more than 1 year) by Adobe to use "file://" before the file location in order to safely access to file while invoking CShockwaveFlash::LoadMovie the movies started loading again.

Removing that "file://" from the path, we get the swf file movies loaded, but that change in this update is a drawback in security on Flash Player 20:
