I was working on an assembly in SolidWorks 2018 which when reopening the assembly file, had no issues.

Windows did an update and now when I open the assembly file, I am prompted to locate the assembly components. This occurs every time that I open the file.

I am working on my laptop, the secondary system, which is a MacBook Pro running Parallels with Windows 10 Pro.

Any suggestions as to why I have this issue now?
