How to fix it

1. 1. Ask for a save-down

   Copy steps
   1. In the newer Max, use File > Save As and choose the older .max version in the file type dropdown
   2. Do not press Ctrl+S afterwards, which can re-save in the newest format

2. 2. Check the version code in the error

   2. Install the matching release or the latest update for your year
   Did this fix it? Yes No

3. 3. Try Merge or an interchange format

   Copy steps
   1. Use File > Import > Merge to pull objects from the file into a new scene
   2. Ask for an FBX or OBJ export if the .max cannot be saved down
   Did this fix it? Yes No

Symptoms

An error says the file was saved in a newer version, names a modifier version (for example Chamfer), or the scene loads only partially with an 'Invalid File' error.

Why it happens

• Scene saved in a newer 3ds Max year than the one installed
• Modifiers or objects from a newer update (a minor update can also break older builds)
• A corrupted file
