I have been running Internet Explorer 7.0 on Windows Vista for several\nmonths and it was working fine. But today I just installed the "Security\nUpdate for Windows Internet Explorer 7 (KB931768)" and that caused IE7 to\nstop working.\n\nAfter I installed the update and restarted Windows, IE7 will no longer\nstart. Now when I double-click the icon or run iexplore.exe, the web browser\nwindow flashes quickly on the screen and then disappears. Then this error\nmessage dialog box appears.\n\n-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\nFile Download - Security Warning\nDo you want to save this file?\nName: navcancl\nType: Unknown File Type, 2.64KB\nFrom: ieframe.dll\nSave Cancel\n-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\n\ntemporarily, I have three ways to fix it:\n1. retore Vista or uninstall the patch\n2. run IE as Administrator ( which, as a matter of fact, disable the\nprotection mode)\n3. in IE Options->Securities->disable Protection Mode.
