Shell context menu item added to Registry but doesn't appear in right click!

I have an application that adds two menu items to the shell context menu of "jpegFile". I can see that it is correctly added to the registry but in some machines it doesn't appear when user right clicks a jpeg file!

I'm usin开发者_开发百科g [Windows 7] and I'm adding items to registry via my application's setup project.

Any idea why?

Probably caused incorrect registry.

Try registering your extension under

[HKEY_CLASSES_ROOT\SystemFileAssociations\image\shell\Blah Blah] @="Edit with Blah Blah"

[HKEY_CLASSES_ROOT\SystemFileAssociations\image\shell\Edit with Blah Blah\command] @="\"C:\Program Files\BlahBlah.exe\" \"%1\""
