Well last night I was helping Kendall test out the utility. One was made for a 32 bit system and one for 64 bit. I tested both. I have Windows Vista on my 32bit and Windows 7 on my 64bit. 

The 32bit with Vista would not work, but the 64 bit with Windows 7 worked fine.

I told Kendall the results and Kendall said that the 32bit seemed to work with XP and Windows 7 but not Vista.

The 64bit..dont know if it was tested on a Vista or not but it worked good on the Windows 7.
