Are you still launching Zenmap as an administrator? When you install 
Nmap it will add the Nmap data directory to the user's PATH environment 
variable (should we change that to add it to System rather than the 
current user?). When you run as an administrator, I suspect it'll stick 
with the systems's PATH settings and fail to find the Nmap data 
directory. Quickly looking at ScriptMetadata.py suggests to me that 
it'll fall back on the line:

return os.getcwd()

So if you launch Zenmap from C:\windows\system32 or C:\Program 
Files\Windows Resource Kits\Tools then it'll try looking in there first, 
the current working directory. What surprises me though is the reference 
to "nselib", as I can't immediately work out why it's looking for 
anything in there. As David says, it should be trying to list the 
possible scripts, which I believe involves reading "script.db" from the 
"scripts" directory.

I would hope that adding Nmap to the administrator user's (or the 
System's) PATH would work around the issue, if you're able to do that?
