Windows 10: Paint & Paint 3D Can't open HEIC files

Windows 10 Pro Build 18362.

The HEIF Image Extensions show as 'This product is installed' when viewed from the Microsoft Store.

When I double click on a HEIC image file I get

I've tried using both Paint and Paint 3D as the Default App for Image Viewing.

The error message appears to be the same.

I can see a thumbnail of the HEIC image in File Explorer.


Thanks for any help or advice!

Paint 3D cannot open STL files

Please update Paint 3D to be able to open STL files. View 3D *can* open them just fine.

When I open them in View 3D, and click the "Paint 3D" button, it gives this error message:

"We couldn't open Paint 3D. Wait a bit, then try again."

I did, and it keeps failing. So then, I manually go to Paint 3D, and open the file from there. In order to do that, I have to enter "*.*" as the filename, otherwise it won't pop up. The file types dropdown doesn't list STL files. But that's for good reason,
apparently, because Paint 3D says:

"Paint 3D can't read this file. It may be invalid, or in a format that we don't currently support."

So, recap:

1) The file is completely valid, because View 3D can open it just fine

2) Why can Paint 3D not open a file, while View 3D can?

3) Please add this functionality to paint 3D. It's an industry standard file type for 3D models.

This is on Windows 10.0.15063.

 

3D Paint

If that does not work, download the following utility, extract it, launch it, scroll through the list, select Paint 3D then click Remove:

Otherwise, you can choose another program to open and view files that normally open in Paint.

Right click a known file that is currently opening in Paint 3D

Click Properties

Click the General tab

Click Change

Choose Paint or another program.
