Hi!

I need a little more information. 

When you click the EW7 icon are you getting an error message? Does the EW7 splash screen come up and then go away or does it stay stuck on the screen. 

Click on the Windows icon (Start menu) at the bottom left-hand corner of the screen,

Type in "DXDIAG" and click on 'DXDIAG.exe' or 'DXDIAG run command',

Click Yes when a yes/no question appears,

Click on Save All Information.. at the bottom-right of the DXDIAG window,

Save the information under and obvious name such as "dxdiagoutput",

Attach the saved file here

Great!
