AutoCAD LT Crash

[Oleg.Konovalov.SIT]

Hello,

we've faced with following problem while working in AutoCAD LT:

after some time of working it crashes with folllowing message (screenshot is in attachment, it is in Russian though, so I will try to translate is appopriately):

Installation Error, continuing working in AutoCAD LT is impossible.

The reason of that may by deleting or changing of keys register by program Registry Clean, which are essentiail for work. In order to recover essential keys register you need to reinstall AutoCAD LT with function "Installation and unistallation" In control panel of Windows.

AutoCAD LT does not launch after that. it launches after rebooting PC. but after some time the crash with the same message repeats.

Reinstallation of AutoCAD LT did not help.

Will appreciate any help and assistance with solving this issue.

With kind regards,

Oleg Konovalov

Are you using a Windows Registry Cleaner? They can be server based, or built into your anti-virus or anti-whatever applications on your PC. Find them, turn them off, set your anti-virus to NOT scan AutoCAD or it;s files or it's processes and see if that helps.

Thank you for your reply. We switched off anti-virus and the problem still occurs.

Did you reinstall LT as well?

[Oleg.Konovalov.SIT]

Yes. No results. The problem remains.

Okay then, just in case if helps someone: we did solve the issue after formating the entire PC.
