How to add Windows Client packages to fresh NB5220 v2.6.0.1?

Have just installed a virtual NB5220 from v2.6.0.1 ISO.  Configured as master.  All seems ok.

Opened browser to WebAdmin GUI, but Windows client kit is not available for download from master.

How do I make a Windows Client available for download from the appliance?

I guess I'm after something a bit like the v2.6.0.2 Windows Client addon package named:

     SYMC_NBAPP_addon_nbwin-7.6.0.2-SLES11.x86_64.rpm

...but I obviously need the v2.6.0.1 equivalent.

Any ideas?
