Sorry to hear that you're having problems installing AutoCAD 2014, this issue may result on some wrong registration of the VBScript.
Check the Autodesk knowledge Database for a resolution proposition "Installation fails with message "Error 2738. Could not access VBScript run time for custom action"
If it doesn't help you to fix the issue, have a look at the following blog post "Error 2738 Installation,".
That should help to resolve your issue.
thanks......i can install sucessfully....
when i launch the programme...there's a problem...
"FATAL ERROR: Unhandled Access Violation Reading 0xffffffff Exception at e7800004h"
Sounds like it could be a .NET Framework corruption issue.
.NET Framework issues can be resolved using the .NET Framework Cleanup Tool. More information about this tool can be found at my discussion thread here:
