AUTOCAD 2016 no add-ons. Yesterday, saved the file and went out, now it does not open. Writes this: INTERNAL ERROR: !saveres.cpp@440:eGeneralMoldingFailure. What to do now? Please help!
To begin, you must try to recover the file using the standard tools of autocad:
File -> Utilities -> Recover
either by typing at the command prompt
If you still will give this error, then you can try some online service https://onlinefile.repair/en/autocad.html
