Can't mount .wim file using ImageX

I'm having trouble getting my XP .wim image to mount.
I following the TechNet article to mount and modify an image - everything makes sense and I'm not getting any errors.
HOWEVER, when I hit the command to mount my image, ImageX just spits back the info on syntax and flags and even gives an example that looks almost identical to what I'm actually using.
Needless to say, my image isn't mounting [when I check it says 0 mounted images].
Thanks in advance!

[below is my commands and output]
C:\Program Files\Windows AIK\Tools\x86>imagex /mountrw g:\exportedwim\winxpuni.wim 1 c:\mount

I haven't toyed with WIM yet, but it seems you're missing info:

C:\Program Files\Windows AIK\Tools\x86>imagex /mountrw g:\exportedwim\winxpuni.wim 1 c:\mount

I would assume it should be:

C:\Program Files\Windows AIK\Tools\x86>imagex /mountrw g:\exportedwim\winxpuni.wim 1 WinXP c:\mount
