Importing Error Question

I don't think client 4.91 works with ZENworks 3.x.
(if you double check the readme.txt file, I think you'll find more details
about ZEN compatibility)

That was the reason I stayed with Nclient 4.90 sp2.
So try going back to this client - works fine for me and I suspect the
easiest solution.

Now if you are starting to use XP and that is why you want 4.91 client
(I don't know any details about XP/ZEN)
then I suspect you really, really should upgrade ZEN. As I don't allow XP at
this time, ZEN 3.2 sp3 is just fine.

My next move will probably be to ZEN 7 - hopefully to handle Linux work
stations... keep on dreamin'
(or to handle XP ...) You should do your own research to decide next ZEN
upgrade.
(I pay annual fees, so I can decide when to upgrade - but keeping Win2k
workstations, I have no need to upgrade ZEN- yet)
