AutoCAD LT 2014 Crashes on First Command

[bglong]

I just bought a new laptop and installed my AutoCAD LT 2014 on it. When I open AutoCAD LT everything seems to be fine. However, the first time that I try to switch to a different command tab or open layer properties, or anything similar AutoCAD LT immediately crashes.

My new laptop is:

• Windows 10 Pro 64
• 16 GB DDR4-2666 SDRAM (2x8GB)
• Intel® Core™ i7-10510U (1.8 GHz, up to 4.9 GHz, 8 MB cache, 4 cores)+NVIDIA® GeForce® MX250 (4 GB GDDR5)

Could the problem be the graphics card?

LT2014 is not supported in Win10 http://autode.sk/1IY4C2X

It may help if you install ALL of the LT2014 updates https://knowledge.autodesk.com/support/autocad-lt/downloads?release=2014

And these Win10 workaround may help as well http://www.howtogeek.com/228689/how-to-make-old-programs-work-on-windows-10/ plus https://windowsreport.com/autocad-not-working-windows-10/

If not, I see you going back to you old PC if paying for newer versions is not an option.

pendean,

Thanks for the reply and links. I'm working my way through them.

My old PC was upgraded to to Win10 as soon as it was released and LT2014
has been working on it for a few years now with no issues. So, I didn't
consider that as a possible problem. I believe the only differences between
my PC's is that my new one has a newer generation of Intel Core i7 and a
different graphics card.

LT2014 and Win10 is always a gamble: it works for some, crashes and burns for others, works great then breaks for more still. Think of it as a game of chance and time: it will eventually end but fun while it lasts.

Updated or downgraded video cards may or may not help, you have some testing to do on your own as well. Remember, you are running a software coded in the year 2011-2012-2013 on a PC with hardware/drivers/OS that no one planned for back then.

Good luck.

Well, I decided to give LT 2020 a chance, to see if it would resolve my
problem. I downloaded the 30-day trial. I have the same problem, it
constantly crashes on many of my drawings. On others it seems to work fine.
I'm trying to come to a conclusion about what is included in the drawings
that would make some crash. Nothing obvious so far.

File content does seem like a possibility. 

Did you fully uninstall the previous version? What ever was causing the crash may still be there if you didn't.

[pendean]

Open LT2020
Start GRAPHICSCONFIG command then turn off HARDWARE ACCELERATION, see if that helps.

Otherwise get in the habit of using RECOVER command (RECOVERALL command if there are xrefs) to open files for a while to solve file-cotent issues being the culprit.

Don't forget: LT2020 creates newer versions of DWG files that 2014 cannot open unless you save down, and then you might see prompts about your files containing newer content all the time while in 2014.

I uninstalled LT 2014 last night, then shut the computer down. This morning
with LT 2020 when opening some drawings I still get a fatal error that
shuts it down.

[RobDraw]

If you don't think it is a file issue, do a full uninstall of both versions and reinstall 2020.

[bglong]

I turned Hardware Acceleration "off" then tried to RECOVERALL on a drawing
that caused a fatal error. I caused a fatal error.

If it helps any, these are some of the errors I have been getting:

FATAL ERROR: Unhandled Access Violation Reading 0x0000 Exception at
79b62debh
FATAL ERROR: Unhandled Access Violation Reading 0x0000 Exception at
7d7f2eabh
FATAL ERROR: Unhandled Access Violation Writing 0x0000 Exception at

I uninstalled both versions of LT. I also uninstalled Revit, DWG TrueView .
. . everything Autodesk.
Shut down, then restarted computer. Reinstalled LT 2020 and I still have
the same problem.

The error I got this time was:
FATAL ERROR: Unhandled Access Violation Writing 0x0000 Exception at
46EDCB0Bh

[RobDraw]

Have you done a search on that error? There's a lot out there and it doesn't look good on the surface.

[pendean]

You need to take your PC in to repair shop IMHO, you've got bigger issues I suspect.

I followed the earlier suggestion of doing a "recoverall" on one of the
drawings I was having trouble with. That did not seem to work. LT 2020
still crashed. So, I tried the following, and it seems to have worked, at
least for this one drawing.

The "recoverall" suggestion, so that xref's would be recovered also,
triggered in my mind that perhaps if I "recover" the xref's individually
that might help. So, on my old computer I opened LT 2014 and tried to open
each of the xref's. I found one of them required recovery. I next did the
"recover" command on that xref. Opened it with LT 2014 and saved. I then
went to my new computer and the problem drawing opened with LT 2020.
***SUCCESS*** at least on that one drawing.

Hello @bglong,

thank you sharing what helped with one of your drawings. At least one step forward in the right direction! Hope you´ll figure out a way that also works for the other drawings. I guess your progress might also be interesting for all the people who helped so far. Feel free to post here when you learn something new and/or make progress so others might suggest new things on the fly alongside your progress. 

Feel free if you see it fit to mark your previous post as solution (at least with the actions you took for the one file) so others can find that one to start with in case they encounter the same problem.

Keep us here in your topic how it goes!
