Hi Steve,
i tried again with ACW to create a new Adobe Acrobat Reader DC package with same result. I started from scratch plus added the latest patch for the reader within the setup.ini.
Patch was included correctly but still no protected view per default.
In the registry "FeatureLockdown" for protectedview is still missing
With Adobe Reader 11 everything is fine, its our default PDF reader yet and was working from day one.
May i can try your MST copy for Reader?
Regards,
Sascha
