Hello,

I have the same problem importing an FC or FB that have been created in TIA V12 to TIA V13, i get an error message saying "Library is faulty".

P.S. additionally to TIA V12 installed TIA Basic, could it make the problem? because the whole project migrated without errors.

What could it be?

Thanks in advance,
