Know someone what to do if AutoCAD 2012 started with follows error?
"The configured Heidi driver cannot be loaded. Switching to default software driver."
I trought set the new plotter file with plotter manager but without succes.
AutoCAD 2011is going without problem.
Thanks for help
Solved! Go to Solution.
try command _3DCONFIG ==> (button) "Manual Tune" and disable "Hardware Acceleration".
If that didn't work, you could try to install the servicepack (if you haven't yet).
What graphiccard do you have in your system?

thank you for your answer. It help, but I don't know why I must draw without hardware acceleration and support. The ACAD 2011 works excelent with full support of my graphic cart. I have Nvidia FX 1500. I downoaded the last driver for ACAD 2012 recomended from Autodesk on the web - 265.70 - but without succes too.
I have one question more:
Do you know system variable for switch on the dialog window (s)? Iif I will open the drawing of edit the block with attributes then come only command line to the action en it is not prety to work.
Thank you very much for answer.
>> but I don't know why I must draw without hardware acceleration and support
You don't need to have it disabled, try to reactivate it now, maybe it will work. Sometimes when installing a service pack for AutoCAD or when installing a new driver of the gc that deactive/re-activate is a good point to get rid of some config-data-loss in AutoCAD:
I hope that you didn't install the nVidia performance driver ==> if so try to deinstall it (and maybe a repair-install of AutoCAD may be necessary.
>> Do you know system variable for switch on the dialog window (s)?
For opening/saving drawings it's FILEDIA (look also >>>here<<<).
For editing block-attributes there are the following sysvar's to check:

There are various suggestions posted on the forum on this issue. I understand that when launching AutoCAD 2012, it shows the error "Heidi Module Load Error. The configured Heidi driver cannot be loaded. Switching to default software driver."
After a bit of research with our development team the original error in this case with the Heidi Module error is a built in safety net. What happens is there is a known issue with Direct X 9 that causes a disconnect between the video card and the operating system when going to a sleep or screen saver mode. AutoCAD disengages from the video card Heidi module when this problem occurs. This is why you get the error.
AutoCAD does this to prevent a crash and loss of information. If it did not disconnect from the Heidi module and use its internal graphics AutoCAD would crash.
Basically this is an installed safety measure to prevent a crash with a known issue between the OS and the video card. Only certain cards have this particular issue when going to the screen saver or sleep mode. While they work properly otherwise this error message is nothing more than an alert and annoying. When the computer comes back from sleep the video card and OS reconnect and everything is put back to normal.
Heidi errors like this have to do with the video driver on your system. Often simply uninstalling and reinstalling the video driver will fix the problem. Aside from getting the current driver from the manufacturer's web site, you can also check your video card and driver against those that we have tested and certified:
*Update graphics cards drivers
*You could also try going to your Options..."System Tab"...Select "Performance Settings"...try turning off Enable Hardware Acceleration...
*Perform a Windows Update to install the available fixes from Microsoft.

Thanks for recomendation. My AutoCAD 2012 works if Enable Hardware Acceleration is OFF only.
I uninstaled the graphic driver and reistalled new one but the problem is the same.
The switch off some parts of the hardware acceleration make the colapse of AutoCAD.
If I modified the dimesion style in dimension style manager then it's was wery dificult work. After each clic of the mouse come the window with error message.
I work more efficiently with AutoCAD 2011.
I hope that new version of the AutoCAD will be better then 2012.
I have exactly the same problems as other users. I am very dissapointed with this "version" generally, so I have to use version 2011. I hope that the new version better. In fact, you dont have to change anything in older version, we will pay anyway our subscription. Rearranging the icons and commands is very unnecessary.
just luck that i stumbled across this thread. i came across this error just a few days ago for the first time, caused by 'switching users' in windows 7, so thanks for the information Shiny.
The Heidi Module load error can sometimes be fixed by reinstalling the DirectX components that are included on the AutoCAD installation disc. I have seen this problem a few times in the past and it can manifest itself a few different ways. If some of the DirectX components which are required to run get uninstalled or are corrputed than the hardware driver will not be able too run.
On the AutoCAD Disc:
I am not ensuring this will fix your issue, only if the problem stems from missing DirectX dependencies.

I removed and complete new instaled AutoCAD 2012 from installation CD and it work without error message.
The graphic driver is accepted too with full support.
SP-1 download OK too.
