LT version is what?
Windows version is what?

What changed on your PC or network recently or over the weekend?

I have the same problem in 2017 and 2018 versions.

My Windows version es 7 Professional. 

I don't think anything change over the weekend in my computer.

Hmmm, I personally have both also installed in WIndows7 so I can confirm "nothing has changed" but they are working fine for me. Where any updates to other software installed? Check/find out using Windows System Restore feature, it ought to list updates and patches installed.

Does this PC still have, or used to have, AutoCAD/LT2012 on it?

A quick search around these forums seems to suggest this painful fix as one solution https://knowledge.autodesk.com/support/autocad/learn-explore/caas/sfdcarticles/sfdcarticles/How-to-r...
