ZCM 2017 Update 3.
One Linux Primary and one Windows Primary.
MDT server on Win2016.
Trying to upload WIM-files in MDT-bundle from MDT server.
zcc-helper works fine. Java installed.
First try I get to chose files and press upload. Stands forever "uploading".
After one hour I break it.
Trying again.
Now get the message "zenworks exception while checking pre requisites for imaging file upload".
Do not come so far so I can chose file to upload.
Running IE as administrator.
Restarted server.
Everything else in ZCC (remote and other things) works.
