Question Error opening webp graphic files in IrfanView

[kacper6768]

When I want to open graphic files with the webp extension, the following message appears

Sorry, this Plugin/feature is not available in IrfanView APP version.
If you need it, please install normal version of IrfanView and Plugins.
[64 bit]

I use Windows 10 Pro 22H2 64 bit and 64 bit IrfanView from Microsoft Store https://apps.microsoft.com/detail/irfanview64/9PJZ3BTL5PV6?hl=en-us&gl=US but I would like to use this from Microsoft Store version instead of installing the normal version of IrfanView
How can I install all plug-ins for IrfanView in the Microsoft Store version?
Programs from the Microsoft Store update automatically and do not clutter the system.

In the latest version of IrfanView 4.62 from December 9, 2022, there is an option to enter the registration code

Are any new features added after registering this IrfanView?
What is the difference between a registered and unregistered version?
Why was the option to register this program added?

This, in v4.59 32bit, in Win 11 Pro.

You can probably download and apply the updates directly from iview.

File association should only affect what happens when double-click an image file from windows explorer.

When that's said I've never tried to install Irfanview from the store. I wonder if webp images are supposed to be natively supported without the plugins package?

Have you tried to simply download and install the plugins package and see if that helps ?
