FATAL ERROR unhandled access violation reading

hey,

 

so i've been getting this pop up window everytime i try to open autocad today. yesterday night i was using it fine.

 

 

now whenever i try to open the program, it says "fatal error unhandled access violation reading b14c4b12h"

i sent an error report to autodesk and they suggested a patch. and after restarting my pc its still not working.

i have win8.1 with autocad2014.

 

it pisses me off koz i have school assignments to do and it's not working 😞

Thanks for your help.

SCNR: but you had time to install Win 8.1, an OS that is not supported with AutoCAD 2014 (yet).

 

If AutoCAD was running ever with 8.1 then look what updates Windows has installed from yesterday to today and uninstall them.

I don't know anyone running AutoCAD 2014 on Win8,1 ... but I read some info's about troubles with Win 8.1

 

So the question again is, what changed from yesterday to today on your system?

Was it the update from Win8 to 8.1 (or was the update to 8.1 earlier and AutoCAD did run with that)?

...or any other (Windows internal) updates?

...or any software installed?

i did restart my pc this morning and it did automatic updates

im attaching a picture of the recent updates. it has to be the ones from today because it was working perfectly fine yesterday or the days before.

Hi,

 

as the display driver was updated you might try to start AutoCAD without hardware acceleration, see the startup parameters therefor >>>click<<<, use the /nohardware parameter and try to start AutoCAD with that.

 

If that does not help uninstall the last two updates (or the last three ones), disable automatic updates, restart Windows and try then AutoCAD.

Hi,

 

>> its still not working

Again the question: you had AutoCAD running free of errors on Win8.1?

 

>> is there any version of autocad that will work??

For now I don't know any offical statement from Autodesk about what applications are supported for Win 8.1 and which are not. For AutoCAD only release 2014 (and 2013 with service pack 2) are tested with Windows 8 (not 8.1).

 

So the only real chance I see is to wait for servicepacks or reinstall Windows 8 without the update to 8.1

Hi,

 

one additional idea: create a new user for your Windows (with admin permissions), login with that new account and try AutoCAD to start.

In case you have not resolved this issue yet....

 

Update the video card driver from the manufactures support website, I just did it and after that, Autocad 2014 worked fine under windows 8.1
