When rolling out ChromeMailer to the people on the wild internets, some reported problems with missing mailto: handlers in registry. If ChromeMailer redirected you here, please see the steps below to repair your mailto handlers.
NOTE: YOU ARE RESPONSIBLE FOR THE CHANGES YOU MAKE IN YOUR REGISTRY!
There’s two ways to fix the issue:
1) Download fix_mailto.reg , (right click -> save as…) then double click it to install. It will recreate all required nodes.
2) Manually. Open Regedit (Start / Run… or in Vista type Regedit into search)
click on HKEY_CLASSES_ROOT. right click on it, New > key, rename it to “mailto”, then select mailto, New > key, create “shell”, in shell, create “open”, in open create “command”, in command: New > string value .it will create a key named (Default), double click on the (Default), and enter the following:
a) on Vista: C:\Program Files\Windows Mail\WinMail.exe /mailurl:%1
b) on XP: C:\Program Files\Outlook Express\msimn.exe /mailurl:%1
This will reset the mailto: protocol handler to Windows default settings. If you now want to use ChromeMailer, simply run it, press ‘Install as Default Mailer’ and it will work as expected.
