Can't reassociate .swf files to Flash Player Projector...

[AlienDrew]

...or any other app for that matter.

Info:

• Windows 10: Version 1803
• Running the files works if I use "Open with" (but trying to set a default program doesn't work)
• I've tried deleting the file extension keys in the registry both for HKEY_CLASSES_ROOT and HKEY_CURRENT_USER, and even using the "assoc" command in cmd as admin, but no luck

This is a Windows 10 issue, not Flash Player. 

I found the following Windows 10 support document https://support.microsoft.com/en-us/help/4028161/windows-10-change-default-programs  If this doesn't work, please contact Microsoft for assistance.

Even trying this doesn't work for me.

You'll need to contact Microsoft for assistance.  This is a Windows issue, not Flash Player issue.
