Error when installing software

[paranoid android]

When I install some software I get a message saying Error 1327: Invalid
Drive Z:\.

What is going wrong? My Z: drive is a NAS hard drive attached to my
wireless router, however, I have tried to install software with the hard
drive turned off, so I'm not convinced that its the problem. Can anyone
help?

Thanks.

Windows Vista Error 1327 (Meaning):

"Logon failure: user account restriction. Possible reasons are blank
passwords not allowed, logon hour restrictions, or a policy restriction has
been enforced. "

What kind of software is it? Perhaps Vista wants to install this software in
C\Program Files. What if you disconnect the drive and Vista will have to
deal with the missing drive, since all the information about the install is
in the registry?
