As of the latest PDF Exchange editor 312 & the last Chrome update 43.0.2357.81 m the Exchange Editor plugin is missing. We have the chrome pdf viewer plugin disabled to pdfs automatically open in PDF-XChange Editor. However, now lumin opens them unless we choose download (then it works). I tried the open with and to add a plugin but PDF-XChange Editor is not listed anywhere.
The issue is company wide for use and I can duplicate it on several machines.
Thanks in advance.
