This was the reply I got that worked-My data execution prevention tab. I didn't know I had one.

This is commonly caused by Windows 7 Data Execution Prevention being turned to the wrong setting.

Start –> Right click on computer –> Properties –> Advanced tab –> (Performance) Settings <button> –> Data Execution Prevention tab –> Change the option to only apply DEP to Windows files and services.
Restart the computer to apply the change, then try to run RealBand.
