You can not start AutoCAD

[emaiolino]

In a workstation that until yesterday afternoon was working properly in the morning these messages appear to us to start without allowing open the software. Someone will it happen? Any solution?

Usually Windows update would cause your autocad to mess up.

Try SYSTEM RESTORE to a day or two before.
