So I have been wrestling with this little issue for a while and figure i would throw it out there

Envirometn

Horizon: 7.5.1

UEM 9.4

Appstacks 2.14

Windows 10 LTSB 2016

I have adobe acrobat reader dc installed on the GM.  I then load office 365 from the appstacks.  If i open outlook and try to open a .pdf, it works the first few times.  Then after that I get a failed to load core .dll.  This only happens from Outlook.  If i preview the file in outlook it works just fine.  If i save it and then open it, works just fine, if i change it over to google chrome to be the default pdf viewer, works just fine.  I have tried all of the fixes from the adobe site of the house, registry fixes for protected mode do not seem to help.

I should just let it be and keep telling them to use chrome or save it then open it, but i figured maybe i can shut the complainer up.  Any help would be appreciated.

Thanks in advance
