"Not Enough Storage Space" error - Acrobat 9 Pro

Hey gang,

I get a "not enough storage space" error message when trying to install Acrobat 9 Pro.  I've got administrative rights and I'm trying to install from my local drive.  Any ideas?  Thanks!  I've attached a screen shot of the error message.

My system particulars:

Windows 7 Pro (64-bit)

Acrobat 9 Professional

8 GB RAM

132 GB free on hard drive

Thanks again,
