Leonardwhat version are you using (incl any service packs)? has this only recently started occuring? have you had any changes (upgrades, new add-ons, new network)? any additional information might help.

Just in case there are others out there still using ACAD LT 2005 (like me) and having this problem, I found that PC Tools Spyware Doctor (v 6.0) creates this exception.

I uninstalled Spyware Doctor and LT worked fine again. Downloaded and installed AVG (like I used to have) and LT still worked fine.

FYI: When I deleted on the temp files in "C:\Users\<user name\AppData\Local\Temp" the problem went away.

I think this error is related to Autocad profiles.
Switch your profile in options, and then switch it back.
If the profile was ever exported keep it readable. (Do not mark as read-only).

Answer: Support File paths in OPTIONS is too long.

I find that the error was linked to some bad code, that was adding a new Trusted Path when autocad started. Eventually, the trusted path list was too long, probably exceeded the maximum allowed by AutoCAD and then crashed it.
Here's what to check.
OPTIONS > Trusted Path (Also check "Support File Search Path", and "Working Support File Search Path") and see that the list is a reasonable length.
If you have alot of repeated paths, remove the duplicates. Then restart AutoCAD.
Sometimes, after deleting the support paths, AutoCAD would crash even after trying to close or apply the Option command, but restarting AutoCAD fixes it.
