Adobe Reader DC and Adobe Acrobat DC in Remote Desktop Services

Hello

This sounds silly, and I am pretty sure I already know the answer.

I help manage and Remote Desktop Services Farm, we are having a very strange issue with Adobe Reader/Acrobat.

We have them both installed on the host server, which to me seems kind of redundant and silly.

Would having both Adobe Reader DC and Adobe Acrobat DC BOTH installed cause a conflict? We are receiving this error when trying to open PDF documents in IE11 -

"There is a problem with Adobe Acrobat/Reader. If it is running, please exit and try again (0:104)."

Since this is a managed environment and we have anywhere from 5-15 people per RDS Host, you can imagine we can't force quit EVERY SINGLE instance of Adobe Reader/Acrobat, well we can. But this pop up happens so much that we are quite perplexed. My solution was a pretty simple one, get rid of Adobe Reader DC and have the users ONLY use Adobe Acrobat DC, I am thinking there is a conflict somewhere, and removing the "FREE" version Adobe Reader DC might help us troubleshoot/eliminate the issue.
