I have the same problem with my computer and i'm looking for a solution. I also talked to the corporate IT administrator but they are not able to help me.
I've administration rights on my laptop.
I was able to remove all JuniperSetupClient instances and login to the web site and launch Pulse to allow installation again. But the problem is still the same.
Iam currently using Windows 10 Pro version 1803.
How could i check the corporate version?
