Adobe DC reader hangs ERP application

After rendering a PDF report the ERP system hangs when trying to close the application. It will close and recover after about a minute. This started happening after the latest update to DC Reader. The version of DC Reader is Adobe Reader DC 2015 release Ver 2015.023.20056, the OS we are using is Win7 and Win10 64 bit, and the ERP system uses Internet Explorer to run, that version is IE11. I know this isn't going to sound good, but I uninstalled Adobe DC reader and installed another PDF reader and the problem doesn't exist.
