QuickView Hit or Miss

Hello All...

I am using an API call to open SolidWorks files using quickview.....which works half the time.   During the Qucikview process SolidWorks will return a error - 1   (Which is described as a generic error)

Is there a property or value that can be set prior to opening the drawing to allow quickview to work?

thanks in advance for any assistance.
