If the program produces an assertion fault inspite of having installed the most recent graphics driver maybe you should do a clean install meaning uninstalling the driver and installing it again, it is not a Software issue, it is Nvidia’s and Windows 7 issue…unfortunately I can’t help you on this.
1/11/2011 : Problem solved the assertion on some machine fails and on some machine succeeds but this has no effect luckily to Scanalyze, so erased it.
