I had to pass a PLN 24 project in version 22 for the needs of a colleague. When opening my file it seems that an extension managing the structure is missing. Can I hope to disable this missing extension from AC22 or do I have to perform this operation from AC24 ?
If you mean that you get a dialogue box when you open the file in 22 that says an add-on is not available, then you can either ignore it (but it will appear again next time you open the file, or you can un-tick the box for that add-on and the information related to it will be removed and you won't see it again next time you open the file.
SAM (Structural Analytic Model) is a new feature in version 24 that does not exist in 22.
So that information is lost anyway.
