We have one user on our system that can't open drawing files every other user can. Whenever he opens a set of drawings, he gets a message "fatal error, unhandled violation access...". Does anyone know what this could be as every other user can open these files with no problems. He is running vista & has tried to open the files in AutoCAD 2009 & 2010 & the drawings are saved at format 2000.

Hi,
we had similar issue in our office few months ago. As I had no time looking for cause, I unistalled Autocad and cleaned all the files associated with it (including regiter) and installed it back again. It's been working since. Dont forget to install all the patches and updates for ur Autocad from autodesks website.

Karol

Hi!
Your error message contains alot of number as well, they are for a reason, if you want us to help , please type all numbers in your error message!

If this is the only AutoCAD installed on Vista, there may be something to do with Vista User Accounts Control, I think you may be interested in trying this and decide if to re-install AutoCAD.
 
1. Go to "Control Panel > User Accounts and Family Safety > User Accounts";
2. Find "Turn User Account Control On or off" and turn off the user account control.

















 
After the UAC is disabled, try to open your drawing and see if there is still the same error message.

I'm not sure if this works but it worth a try.

hey sean ...i have the same issue..i did shut off uac...i am using a plug in of LDassistant that is a lighting design program..it uses DLL features and that is my fatal error...unhandled access violation writing 0x00070 exception at 635dc655h.
Any clues...it craches every time I try top acces the content block that I need to use the program..

If you unload the DLL in AutoCAD, does it still report error? If it stops crashes, it is the compatible issue with the Dll and AutoCAD, contact LDassistant and call for compatible package.

can you give me a better detail of cleaning all files associated, and what in the registry I have to deletse also?

- uninstall Autocad
- delete everyting within "c:\Documents and Settings\(name)\Application Data\Autodesk\AutoCAD 2006\"
- as well delete "c:\Documents and Settings\Karol.HRA\Local Settings\Application Data\Autodesk\AutoCAD 2006\"
- in case the folder in "c:\Program Files\AutoCAD 2006\" was not deleted at uninstall process, delete it
- go to start/run, type regedit. Go to hkey_local_machine/software and delete Autodesk. If you wish you can create backup of your registry (just in case)
- restart PC, install Autocad
it did work for me
