Windows 10: Raw Viewer Extension app does not work for Sony .ARW thumbnails

I have a fast computer and the latest version of Windows 10. I have uninstalled FASTPictureViewer codec from my computer as it is no longer supported and installed Microsoft RawImageExtension. It did not show the images in Explorer so I uninstalled it and reloaded it. Checked with Powershell that the codec is there. Now, as before, Some folders show the RAW thumbnails, but also have the xmp files next to them. Some have mixtures of thumbnails of RAW pictures and icons instead of thumbnails of other pictures. Some have just icons and xmp files, no thumbnails. Some opened with icons and xmp

WIndows 10 Photo Viewer RAW Camera Files

I recently bought a new Sony Mirrorless Camera that has .ARW RAW photo files. Windows 10 Photo viewer says "It looks like we don't support this file format" when I try to open them.

The strange thing is before I bought this new camera, I used a different Sony Mirrorless Camera that had the same .ARW photo files and it worked just fine.

More details:

Old camera: Sony a6000 (RAW files opened in photo viewer)

New Camera: Sony A7ii (RAW files won't open in photo viewer)

Thanks!

 

Preview Pane for Images/Some Thumbnails/Photos not Working Only on OneDrive Folder

The preview pane and thumbnails as well as the Photos app are not working, but only on my OneDrive folder. It works fine on an exact copy of the same files that are not in the OneDrive synced folder structure (and known to Windows as being OneDrive).

• Open OneDrive Folder, navigate to photos directory
• Sony Raw images (.ARW) do not show thumbnails. (I have the Sony plug in installed)
• Double click on a raw file, Photos says "We can't open this file."
• Click on a jpeg file, and with preview window turned on, no preview appears
• Double click on jpeg file, opens fine in Photos, and then the preview window image appears

• Navigate to a directory that is not synced to OneDrive
• Sony Raw thumbnails show up fine. They also show up in the preview window.
• Double click on Raw file and Photos opens it up without problems

• Back to OneDrive photo directory
• Copy raw file to desktop
• Immediately the thumbnail appears and the file can be opened with Photos. The same file that it can't open from Explorer in the OneDrive directory

This is only happening on my desktop. My laptop is fine. Both same versions of Windows 10 Version 1709 OS Build 16299.19

 

Cannot open .ARW Sony A7IV with Windows 7 64B?

What was the complete text of the message that you got when you attempted to update Camera Raw?

Download and install (free) IrfanView: IrfanView - Official Homepage - One of the Most Popular Viewers Worldwide

IrfanView can open ARW files and you can then save them in any desired format.

IrfanView supported file formats: IrfanView Formats For some reason, ARW isn't at the top of the alphabetical list, but it's there:
