How to find the installation directory or executable launch directory?

How do I find the installation directory or executable launch directory of "Pictures Opener - Heic Supported Including Convert"?

I installed it from the Windows app store.

I know how to launch it from Windows 10. And if I've already downloaded the file, I know how to open the .heic file using this app.

But when I open a picture from a web browser (instead of downloading it), such as Firefox, it asks me which program to open the HEIC file from. I then have to browse for the installation directory of this app, and look for the executable.

But I can't find the installation directory, nor the executable.

Thank you!

I had tried HEVC Extensions earlier, but I didn't want to pay for the add-on, so I started looking for free alternatives.

Your link, with the free "HEVC Video Extensions from Device Manufacturer.", worked.

I was then able to view the HEVC files directly in Photos. And I was able to open a file from a web browser and have it open in Photos directly too, without having to explicitly download it.

So this makes it easier, all-around.

I uninstalled the app from earlier today, "Pictures Opener - Heic Supported Including Convert".
