I was installing AutoCAD 2010 that comes with Revit Suite 2010 for a user. The installation was smooth but the microsoft error report dialog pop up upon start up of the application. Microsoft says AutoCAD component has encountered a problem and need to close. After which another AutoCAD error report dialog followed "A software problem has caused AutoCAD to close unexpectedly. I tried the same CD on another dept and the software installation goes smoothly. However, it seems that all the PC within the first dept all has installation problem. I wonder it has anything to do with .net framework, avira antivirus premium edition, firewall or existing installation of AutoCAD 2007? I has tried uninstalling .net framework, disabling antivirus all to no avail. Please help!!
