Yes you need to download all of the files and copy them to one files as per instructions. You need combine all of the files before uncompressing.

7zip can extract tar.gz files on Windows. 7zip is open source can be downloaded form 

http://www.7-zip.org/

I need to copy them to one file -- using command copy /b NB_Appliance_N_2.6.0.1-1.x86_64-tar-split.1of6+NB_Appliance_N_2.6.0.1-1.x86_64-tar-split.2of6+NB_Appliance_N_2.6.0.1-1.x86_64-tar-split.3of6+NB_Appliance_N_2.6.0.1-1.x86_64-tar-split.4of6+NB_Appliance_N_2.6.0.1-1.x86_64-tar-split.5of6+NB_Appliance_N_2.6.0.1-1.x86_64-tar-split.6of6 NB_Appliance_N_2.6.0.1-1.tar (cited similar example from https://support.symantec.com/en_US/article.TECH205913.html)  then extract it 7zip can extract tar.gz files on Windows 

I m correct, Nicolai?

Yes - you are correct

The tech note also mention :

   Use the Windows unzip utility to extract the NB_Appliance_N_2.6.0.1-1.tar.

7zip is open source, winzip is comercial software.

Yes, you can run LiveUpdate from your OpsCenter server, not a problem, you just need HTTP server there.

Also, as you mentioned you have 6.5 clients, remember that LiveUpdate was optional add-on in 6.5 so if it was not installed you may need to upgrade those clients manually

Please verify the cksum of the individual files before joing. I don't like the 7zip warning.
