Cannot "open" files in Sysprep folder?

Hello,

I'm in the trenches trying to develop a Windows 7 image for work. This is what I've done so far:

I installed Win 7 64-bit on a test computer and did some customizations ( added programs, etc..). I then ran sysprep from C:\Windows\System32\Sysprep... and the process completed just fine. Okay, so I decided to do further customization of the sysprep process by creating an unattend.xml file using WAIK... Ran Sysprep again - not bad results - but I now notice when I attempt to open any log files ( Pather folder ) or "open" the unattend.xml file I get the following error message:

"Windows cannot find 'C:\Windows\System32\sysprep\unattend.xml' Make sure you typed the name correctly and Try Again"

Yet the files are visible in Windows Explorer...

Can anybody tell me "what's what", here??????

thank you,

adrian
