Tried upgrading a win7 64 client from novell client 2 sp1 (ir7) to v2

During the install, either via acu.exe or setup.exe, I get an error:

"There was an error installing Novell International
Cryptographic Infrastructure (NICI). Error Code: 1612.

Then goes on to say that installation succeeded, but the installation
of one or more of the additional products failed.

I tried downloading client 2 sp2 (ir2a) & get the same error.

Any ideas? Suggestions?
