Hi Brian,

Definitely the .htm and .js not previewing is not related to MoI. The .3dm issue certainly could be. But MoI does not directly control the previewing process, it has a thumbnail image provider that is called by the shell in the background when it wants to generate a thumbnail image.
Hmmm, you recently also installed Rhino 8, right? That will have it's own thumbnail provider so you might see if you have a difference between setting MoI versus the Rhino one active.
To set MoI's one active, run a command prompt as Administrator and inside the MoI program files folder run:
regsvr32 moi_lib.dll
To set Rhino's active I think look for a dll named RhinoHandlers.dll and call regsvr32 RhinoHandlers.dll , some related info for Rhino v7 here:

Thank you Michael for the tips, even though this is likely not a MoI problem.
Rhino 8.1 not installed at home yet. It is funny that the preview problem showed up on Windows 10 pc, and Windows 11 pc, about the same time.
Will upgrade 2 SSD's in a few days.
I recently purchased a "baby" Dell pc for CNC, with nothing loaded yet, (Windows 11).
I'll install a few things and see if preview gets messed up or not, and report back later if anything turns up.
(I only use MoI on one computer at a time.)

So MoI thumbnail viewer only works for recently saved .3dm's???
From: bemfarmer
Loaded existing .3dm into MoI5_Dec1 Beta, and saved to D drive,
and to MoIAppData. They were the AlibreLogo.3dm and an Acorn.3dm
Preview works on them. (They currently show a file type (Icon) of Rhino.
.htm and .js still do not preview, but try to load.
T-Rex.3mf DOES preview.

Explored some mysteries of OneDrive...
Will Checkout Rhino vs MoI .3dm preview...

Hi Brian,

It should work on any .3dms saved since the Mar-28-2023 v5 beta which is the first version of MoI that would save thumbnail images inside .3dm files.
