Can you give more information what happened up to this error? Did you create this file?
Yes I created this file last year in SW 2015. However, my organization upgraded to SW 2017 last month. This is what happens when I try to open files now.
Do you get this message when you open any type of file?
The message you show was for an assembly.
Are your templates and files in the same directory locations?
Do these files open on other computers that are running SWX 2017?
File might be corrupted - I think you'd better send the file to your VAR for further investigation
