Hi coold10 and welcome.

Have you reinstalled the Camera Driver? The Camera Driver works for all operating systems (XP, Vista, Windows 7 etc).

Download the 'Original Drivers Package' from here: -

http://www.sony.co.uk/support/en/product/VGN-CR21S_P/updates

You will find it under the 'Preinstalled Drivers and Utilities - Windows Vista' section.

1. Right-click on the downloaded CR2_Drivers.ZIP file and choose 'Extract All'

2. Extract the Drivers to a folder you can find easily.

3. Open the 'Camera' folder from the extracted drivers and double-click on the Setup File depending on which type of Windows you have installed: -

For 32-bit Windows, run DPInst32.EXE

For 64-bit Windows, run DPInst64.EXE
