I am having a similar issue with Autodesk DWG 2011. I am getting the message the configured Heidi driver cannot be loaded. Switching to default software driver.
Once the client clicks the "ok" button they are able to continue.
Some of my clients have dual monitors and this is where they are getting the error message when they launch the program. I am not getting the error message on workstation with a single monitor.
I have given admin access and change the hardware acceleration as well and still getting the pop up.
We have also re-built the workstation with the most updated drivers.
Any suggestions would be great.
I found the only way to stop the warning from coming up each time is to disable the harware accelleration. It's an icon (lower right corner) of an integrated circuit, with a lightbulb beside it (beside the lock icon). This applied to both 2011 and the 2012 installs.
I don't notice anything different from the previous install on an old machine and the new laptop was supposed to be a "workstation" (EliteBook 8730w). Not sure why the hardware accelleration doesn't actually work though.
Just an update to mention that the same issue exists for ACAD Electrical 2013, where you must disable hardware acceleration to eliminate the bothersome error message.
I have just tried to upgrade from Trueview 2011 on an XP desktop to 2013 64 bit on a Win7 64 bit desktop and get the Heidi message whether the accelerator is on or off. Problem is I can open the cad file but there is no dialog box associoated with the measuring tool and so I can measure but get no answers....
