Question

Windows 10 x64 IE11 Flash 20.0.0.306 - Flash will only work when IE is "Run As Administrator"

This is affecting hundreds of PC's at our school division. Flash worked fine when the pc's were originally deployed a few months ago. I've confirmed that ActiveX Filtering is NOT on. I've confirmed that the Flash IE Add On is enabled.

My research leads me to believe that it is a permissions issue, either on the file system or in the registry, though I've not been able to discover where. I found a post on the Adobe site regarding resetting Flash permissions using Subinacl.exe and a script called reset_fp.bat, tried it, some of the commands in the scripts completed, many failed. After completion results were the same, Flash only runs when launching IE11 using Right Click - Run as Administrator.

I'm wondering if there is another way to reset the default Flash permissions? Is there a way to "reinstall" the built in version of Flash?

Oh yes, I've also tried removing the latest Flash Updates. As well I've unchecked IE11 under Control Panel- Programs - Turn Windows Features On or Off. Rebooted, then reckecked IE11 to "reinstall" it. Still no luck.

Flash works fine in Edge by the way, however Edge is not an option for many of the sites we use.

Any assistance is greatly appreciated.

Solved... Not entirely sure why but adding the effected sites to the "Trusted Site" list worked.

Was Flash failing to play on all sites?  Or just the ones that you ended up adding to the Trusted Site list?

We are experiencing something very similar and have tried many of the same things.  We are in the middle of rolling out Win 10 and use the same version number of Flash on both our standard Win 7 and Win 10 machines.  We only experience the issue when using IE 11 on Win 10 .  All other OS's and browsers work fine.  Our current standard is Flash 21.0.0.213 and when that failed on WIN 10 we upgraded to 22.0.0.192 with the same results.  The symptoms only appear to affect IE11 and have no impact on Edge or Chrome and like previous posts not all of our business is able to use an alternative browser as a workaround.  When users navigate to a site with rich content the browser will freeze.  In some cases it will eventually crash the browser, but most of the time it freezes and will not allow access to any of the menu settings.  However, if we (right click and "run as administrator") IE will run the page including the rich content as expected without crashing or freezing.  As you can imagine informing 55k users to always launch their browser using run as administrator is not sustainable and always running the browser as administrator is a security risk.  Is there a known permanent solution to this besides waiting for all content providers to migrate away from Flash?
