Can't calibrate digitizer

Hey everyone.

I rcently bought 2 UMPC's from craigslist. A Rover PC U700 and a
Sony VAIO VGN-UX280P.

The Rover PC came with Windows 8 but I did not like it so I installed
Windows 7 32 bit and all went well. I wanted to calibrate the touchscreen to work with a stylus so I went into Start/Control Panel/Harware and Sound and then Tablet PC settings on the bottom.
It brought up the digitizer and all went well.

The VGN-UX280P came with Windows 7 but I could not find the
Tablet PC settings anywhere on Windows. The touchscreen worked
but the calibration was off. I searched online for a solution but found little or nothing. So, I installed Windows 7 myself (the same build I put on the Rover) and when I go to Start/Control Panel/Hardware and Sound there is no Tablet PC settings.

I went under Programs and Features and made sure Tablet PC was checked as a feature (and it was). I even tried unchecking/rebooting/rechecking/rebooting the Tablet PC and when I go back to Control Panel no Tablet PC Settings.

I would REALLY like to calibrate the stylus. Anyone have any idea on how I can fix this??

Any help would be appreciated.
