I'm evaluating Maya as a 3D Modeling solution for the company I work for. I have a good amount of experience with AutoCAD and in doing research, it appears that I may have an avenue of modeling by importing from a CAD drawing through Alias Studio 12.

I installed Studio 12 only to be met by this error when I tried to open it:

You do not have a user_data directory in:
c:\\[network location]
and do not have permissions to create one
in that directory.
You may not run Studio 12 without a user_data directory.
Check your definition of ALIAS_WORKENV.

I can't even get Studio 12 to open because of this error.

Upon further research on the 'net, I found that it's a setting that I need to set, but don't know where to find it:
"An alternate location for the user folder can be specified
by setting the ALIAS_WORKENV environment
variable. To learn more about setting environment
variables and Alias environment variables, see
Environment Variables in the Technical section of the
online documentation."

Where do I find the online documentation? Is this something that needs to be set within Maya or within Studio 12, or in some other windows environment?
