AutoCAD 2014 not working on Windows 8.1 after successful installation

[abhishekn2510]

I installed AutoCAD 2014 on my Windows 8.1 using online installation. Program was installed successfully. How ever when I try to open the AutoCAD application, it shows "FATAL ERROR: Unhandled Access Violation reading 0x0020 Exception at c50e5c21h" and application cannot be accessed furthur. How can I solve the issue?

I tried installing AutoCAD 2014 SP1, it showed "This app cannot run on your PC".

Thank You,

Abhishek N

ps. I had AutoCAD 2010 on my Windows 8, it was working fine, then upgraded the OS to Windows 8.1, then AutoCAD 2010 showd the same error. Now, the same problem persists with AutoCAD 2014 fresh install.

Hi Abhishek,

Sorry to hear that you're having problems installing AutoCAD 2014 on Windows 8.1.

This issue may result on some incompatibility issue with your hardware configuration, please make sure your computer meets the requirements "Find Recommended Hardware".

Can you please try to start the application under "Diagnostic Mode"?

Go into Msconfig

Start/Run.Type in Msconfig.Under the general tab selects "Diagnostic Startup".

If it works under diagnostic mode, try to localize which "service" may prevent the application from running properly.

Note that ACAD 2014 is not officially supported on Windows 8.1 "System requirements for AutoCAD 2014", as we do "not recommend" to upgrade your OS before having the corresponding product officially supported.

However you can expect the next service pack to make the compatibility with Windows 8.1 work.

Regards

2015 is the only AutoCAD product supported in Win8.1.

Good to hear that. Have any idea that, other autodesk products like 3DS Max have issues alike AutoCAD in Windows 8.1?

Many thanks for the brief reply. I did try all the above, but couldn't sort out the issue. It seems, majority of users are facing issues with Windows 8.1. Hopefully the next service pack will bring an end to this.
