NAL window - Client 49SP2e

Hope someone can help,

I have installed the client as normal onto Windows 2000 SP4, but when the
Laptop boots up the NAL window does not open, instead i get an error
stating that it cannot find the files specified. When attempting to run
Nal.exe or NALWIN32 from the run prompt i get the same error. Has anyone
else had this issue.

Note, we run our Novel delivered Applications window from the PC itself to
speed up login.
