Hello,

I've recently upgraded to SolidWorks 2025 and found that files that I had created using SW2024 and now updated to SW2025 cannot be saved to the older revision of SW2023 or SW2024 due to this bizarre error.

I have SW2025, trying to save to either SW2024 or SW2023, which is within two releases. It does not matter if I try to do this directly as a save-as or as a pack&go.

Thank you,

Alex
