14: Why does Windows Remote Assistance (MSRA) report “PPAppLockdr64.dll is not designed to run on Windows or it contains an error” 0xc000428 ?

PolicyPak AppLock is the feature in PolicyPak Application Manager which GRAYS or REMOVES UI controls in well-behaved Win32-applications.

Here's a video showing how to STOP the AppLock feature to bypass the problem... video talks about Chrome.. but.. yes, this video will explain how to work around the problem and stop the AppLock part of PolicyPak Application Manager.


In general it is NOT recommended to Stop AppLock, but for now, this is the only workaround. Its up to you if you want to stop AppLock and get back applications like MSRA which have issues.

Error message seen is below.
