please help, I don't understand the cause of this error or how to fix? it suddenly appeared without me doing anything for it to happen, please see attached image
it looks like one of your files was saved in SOLIDWORKS 2017 ,
I would see if you have a copy form 2016 you can replace it with or make sure you are on 2016 SP5 and you may be able to work with the file as the last service pack of the year can generally open the next releases files with limited functionality.
How come it is saved in 2017 while all i have is solidworks 2016 sp2? Can i be able to know in which version it is saved? Can i re-save it in my current version or restore my old saving?
Unless you have a recovery file or PDM system good luck.
