We are still using novmenber 2017 sr5. We are working for uppgradering and I downloaded desktop version April 2020 sr4 and installed that on my computer. After that I can't open application on access point, instead I get message iis_authenticate could not be open. I read that desktop and plug-in must be of same version so I removied desktop version April 2020 and installd desktop version november 2017 sr5. I have removed plug-in and installed it again. But I get same result when I open a application in access point iis_authenticate could not be open.
I can't upgrade publisher and plug-in nearest month.
