I'm getting an NMAS error when installing IDM 3.5.1 on Netware.

My config is:

OES2 Netware (sp7)
Security Services update 2.0.5
NMAS 3.2.0.1

The install gets toward the end and then I get and error in the GUI. It
points to the ni.log which is below...

the install bombs out after this so I'm not sure it completes.

Any Ideas?

Thanks as always.
