Just installed W11, clean install. I installed Irfanview for my image viewer and simple editing. However it will not associate jpg and png file types, although it did for many other file types. I tried installing as an Administrator. I tried setting associations from within Irfanview. I tried going to the Default Programs control panel and tried to associate jpg files with Irfanview. JPG is not listed in the file types. Nore is png. Both have been taken by Photo Viewer and nothing seems to make it give it up.
I understand that VLC video viewer is also having trouble with setting file associations.
I am using the 64 bit version of Irfanview, latest version. I am using Windows 11 Home.

I think I fixed it. I went to "Apps and Features", found Microsoft Photos, clicked on the hamburger menu on the far right, chose "advanced options" went to the Reset section and performed both the Repair and the Reset functions. After that I was then able to associate jpg and other file types to Irfanview.
Are you running the version of Irfanview from the Windows Store? I think you need to use that version for W11 rather than downloaded exe file.
Hi Amdkt7
Sorry, I was offline.
It is very strange that the 'Change' button is missing on that Properties Dialog box.
Open the Settings App, then go to Apps - Default Apps
Scroll to the bottom and click 'Choose a default by file type
Can you then select the jpg file type and associate IrfanView from there?
I believe that is where I find that jpg, png, and a few other extensions are missing. When I am home again I will go through that process and try to get a screen shot. If I could find the extension then I could probably create the association.
I think it fails because of the issue with the file types being missing. VLC player also has this problem. When you use the "Choose a default by file type" in the settings panel you can not find some of the common file types such as jpg and png.
