Given that Norton actually support their AV product on W2K, have you asked them? Or searched their FAQ/knowledgebase? or searched this forum for that matter..?
 
I use Norton, and I've used LiveUpdate, and it works fine...

NAV for Win2K is working great here too. In fact, I can back up personally what Yuppie said about Symantec getting their product to run with Win2K: I found a memory leak in NAV for Win2K (RC2 days) about three days after I bought it. I contacted Symantec and notified them of the problem with the memory leak and within two days, they released a program update that corrected the memory leak. To say the least, it restored my confidence in Symantec products.

Check symantec's web site I have had the same error. I found the solution at their web site.

Does anyone know if you can install NAV from win Norton System Works 2000 into win2k? It would suck if I had to buy another version.

To Mark W:
Norton Systemworks 2000 is a Win95/98 product. NAV2000 only works if you use the NT/WIN2000 version. Contact Symatec to see if you can get a upgrade purchase.
