AutoCAD LT

[#1]

I did not clean registry values.  I was not aware that removing the program wouldn't remove registry values.  Could you provide some information on how to do this without screwing up my OS?

I am on a laptop, but not an underpowered one.  I should have no problem running the aero theme, but I will try it as my options for troubleshooting seem to be running out.

This is old but still applcable with the corrected version numbers, Autodesk recommended uninstall and reinstall procedures:

Also change LT2013's Hardware Acceleration setting from whatever you have currently, see if that helps.

Just an update:  I changed to a non-aero theme and the error changed to:

FATAL ERROR: Unahandled c0000409h Exception at e2b91030h

Are you running a certified video card driver on a supported card?

[#5]

yes,

I updated my video driver after this started happening.

And the second part of my last reply?

[#7]

Hi,

I want to refresh this case.

I have this kind of problem when I try to print sth from AutoCAD 2007 and AC 2008 on another machine.

I always get this kind of communicate:

FATAL ERROR: Unhandled c0000409h Exception at 3300e012h - AC 2007

FATAL ERROR: Unhandled c0000409h Exception at 675ddaf2h - AC 2008

Do you have any idea what can be a solution?

[#8]

The error messages mean little, sorry.

What changed recently on the PCs where the two versions are installed: new drivers for the printers, new printers, new server where the printers are accessed? New Windows or new PCs? Please try and find out what changed and report it.

[#9]

I'm not sure that you understand me correctly.

I have AutoCAD 2007 since 5 years on one computer and AC 2008 on another computer.

Previous all was ok. Now I have this kind of problem.

Windows updates?

.NET updates?

Look at the System Restore log and see if something has been updated on your system.

As has been asked: What changed?

It worked for five years so why not now?
