Can't use "Open with…" to use latest version of Avidemux

[hhul]

Here is explanation and solution:

Find the registry key for the application you wish to associate, lets say for Notepad++.exe in \HKEY_CLASSES_ROOT\Applications\notepad++.exe \shell\open\command\

Check if the .exe path is right. If not, then change the path to the correct one.

After doing this, you can now go to the file you wish to associate and use the standard way Open With and choose the program you wish to open.

Explanation:

This issue happens when Windows gets confused about the filepath for a program, as file associations are handled using only the base executable name of a program (source).

This bug can be caused by:

    Running multiple versions of a program (i.e. Notepad++ and Notepad++ Portable)
    Moving programs to different folders.
    Changing drive letters
