I am running ZCM 10.3.3. Attempting to upload an executable. Zenworks
always displays "A newer version of Novell File Upload extension is
available. Click here to upgrade". I found TID 7007866 and followed
the directions, but now I get this error:

"Firefox could not install the file at
https://zenworks.msktd.com/zenworks/...euploadext.xpi
because: Signing could not be verified.
-260"

How do I get this to work?

Regards,
Ken Etter
