unable to remove/deselect file associations

[izumitelj]

I am unable to remove/deselect any file associations from the list.
(Settings > Integration > Run the File association tool)
I'm experiencing this on XnView MP v.064 / Windows 7 x64

Idea/fix/workaround, anyone.
Thank you

I have that problem with XnView Extended 2.1.3 on Windows 8.1
Clicking on the list with the file associations to select or deselect them, is like clicking on a picture. Nothing happens.

If you add a hash key, you are able to unselect extension??

I don't have any hands-on experience with Windows 8, but it is my understanding that the hash key can only be added by the system, and that there's no way to associate file types during the installation of XnView or from within XnView's options (“System integration”) any more

The file type and URI association model has changed in Windows 8. Apps are no longer able to programmatically set themselves as the default handler for a file type or URI. Instead, now the user always controls what the default handler is for a file type or URI scheme.

There are three ways your application can be surfaced once it registers. Choose the option that is most appropriate for your application.

1. Default contention
   • Description: Applications that contend for defaults will be proactively promoted to the user automatically by Windows.
   • Recommended for: Apps that wish to be the considered for selection as the default handler for a file type.
   • How to do this: Register your ProgID under
     • \SOFTWARE\Classes\[FileType]\OpenWithProgIDs
2. ‘OpenWith’ list
   • Description: Applications that are added to the OpenWith list (but don’t contend to be a default handler) appear on the OpenWith list, but are not proactively promoted to the user.
   • Recommended for: Apps that are used as occasional viewers or editors of a file type, but not necessarily appropriate as the default.
   • How to do this: Register your ProgID under
     • \SOFTWARE\Classes\[FileType]\OpenWithList
3. ‘See all’ list
   • Description: Applications that register to be included in the ‘see all’ portion of the OpenWith list are available to be chosen for any file type.
   • Recommended for: Generally not recommended, except for apps that are universal viewers for all file types.
   • How to do this: Register your application under \SOFTWARE\Classes\Applications, and be sure to not add a ‘NoOpenWith’ key.
