2009 image installation closes without installing

I created an Administrative Image that is stored on a network drive.  The Image is designed to update our existing 2007 installation.  I open "StartSWInstall.hta" and click "Install SolidWorks products now".  The install Installation Manager opens and it says "Starting the Installation Manager."  But then closes in less than 5 seconds with nothing happening.  I've only tried it on one computer so far.  Does anyone know why this might happen?SolidworksAdministration
