Driveworks Express output to specified location

I've just learned how to struggle through Driveworks Express (DWX) and caught a snag. I'd like DWX to output the new model on my desktop, or anywhere other than the original model's folder. That was I don't have to run the configuration, then move the output to where I want. This is supposed to be a tool for everyone here at work. I make the configurable model, and it makes it easy on everyone!

I found this info on DWX website in the forums: http://driveworksxpress.blogspot.com/2008/12/overriding-master-name.html

Ok, that's cool. I can give the output a prefix! First step, make sure it works, so I enter:

     ="*" & projectname & "dwx box"

where projectname is the variable I enter with all the other dimensions. Sure enough, it give me a file like:

     ABC123dwx box.SLDPRT

Next step, put the path of my desktop in for the prefix. I thought I'd tricked DWX

     ="*" & "C:\Documents and Settings\Matt\Desktop\dwx box"

                                             or

     ="*" & "C:\Documents and Settings\Matt\Desktop\" & "dwx box"

and I get the error:     The value for filename contains invalid characters for a filename

I tried "C:\" and just "C:" and "\", they all give me the error. I can't put the output file in another folder without the ":" or "\" characters. I can't map a new drive letter for my desktop or anything else I have thought of.

Has anyone found a trick to make it work? Undoubtedly DW has included this limitation so you will purchase the full version instead of Express.
