I was trying to install AutoCAD Mechanical 2012 x64 on my Windows 8 CP x64. but the installer couldn't install .NET 4.0, as it is in-built in WIndows 8, and the setup failed. I edited the setup.ini file to exclude DOTNET4 from all the components' prerequisites and then the AutoCAD installed fine.
then, after launching the program, working and then upon closing, I was getting the famous 'unhandled access violation error', followed by a "send error report to Autodesk" with my AutoCAD Mechanical 2012 x64 on Windows 8 Consumer Preview x64. however after much searching on the net i found the following solution to be helpful:
1. open Notepad as Administrator (important!)
2. open the file: "C:\Program Files\Autodesk\AutoCAD 2012\acad.exe.config" (you will have to select "All files" from the open dialog box to see that file)
3. in the 3rd line - "<startup useLegacyV2RuntimeActivationPolicy="true">" change "true" to "false". leave everything else as it is.
4. save the file.
5. Start AutoCAD.
the AutoCAD then worked absolutely fine.
Now, I'm getting the same problem in AutoCAD Mechanical 2013 x64 and the same steps are not helping...at all!
the installation went absolutely fine without the need to edit setup.ini this time. But this bug won't go now.
Can anyone help me to remove this bug? I know Windows 8 is not officially supported by AutoCAD but well, it worked fine and it should work fine now! any genius coder out there??
I even tried installing in Windows 8 Release Preview, but same error. I wonder what is taking so long for Autodesk to come up with the Windows 8 support. They should issue some fix for Windosw 8 asap, it's high time now!!
It is my experience with AutoDesk that they will not fix bugs in Windows versions until it is released to the public and out of beta (preview) stage.
that's stupid...nvidia has already been releasing drivers for Windows 8 even since Developer Preview came out. now how can i use autocad 2013? huhh...m not going back to Windows 7!
I had the same problem on Windows 8 Release Preview.
The .config-edit made AutoCAD crash even faster - about half a second after showing the spash screen.
Just setting compatibility mode for AutoCAD 2013 to Windows 7 compatilibility solved it for me.
Only seems to be a combatibility problem with new computers running Windows 8 and AutoCAD 2012. Export your licence prior to installing Windows 8 and import it to get going again when Windows 8 has been installed.
"I edited the setup.ini file to exclude DOTNET4 from all the components' prerequisites and then the AutoCAD installed fine."
