Hi @Anonymous,
Forgive me I am misunderstanding your question due to bad translation, but I understand that your AutoCAD is crashing or shutting down. Is this happening with all drawings or just specific ones? Please try running AUDIT and Purge to see if that helps.
Please also tell me your exact version of AutoCAD LT by typing ABOUT at the command line. Also, I would like to know your exact Windows version (type WINVER) at the Windows command line) and the graphics card make and model that you have installed.
When your application crashes, do you have the chance to submit a crash report? If so, please share the report number(s) so I can research them.
Please select the Accept as Solution button if my post solves your issue or answers your question.
