You mention 'solo' for the project. Do you mean the 'Solo Edition'?
Judging by the name of the label, I would guess it is from version 22 of either Solo or 'regular' archicad. You either need migration libraries if you are using a newer version of archicad or maybe there could be a difference between AC22 solo and 'plain' AC22.
