No default email client found

Many HP Scan applications complain that no default email client is found, even though you have defaults set and have something besides the desktop version of Outlook.
*Even App Version of Outlook will not work

Tested Apps
- Outlook (desktop version) - Just install and should work
- Outlook (App Version) - Does not work (It's Lite version that is basically browser version)
- Thunderbird (Free Application) Does work, but Regedit change needed

Thunderbird

In search type: Registry and select 'Registry Editor' to open.

Locate

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
  • Right click on 'App Paths' and select 'New' > 'Key'
  • Name it: outlook.exe

This will create:

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\outlook.exe


Locate:

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\thunderbird.exe
  • On the right it will have two ab listed names (Default) and 'Path' both of type 'REG_SZ'
  • Double click on 'Default' name to open 'Edit String' window.
  • Do not edit anything.
  • Copy all the 'Value Data' - highlight all text, right click and select 'Copy'
  • click on 'Cancel' to close as you do not want to save anything.

Locate

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\outlook.exe
  • In 'Name' column it will say Default.
  • Double click on 'Default' to open the Edit String window.
  • In the 'Value Data' text box, Paste in the copied text - right click and select paste.
  • click on 'OK' to save
  • Right click on the App Paths\outlook.exe and select 'New' > 'String Value'
  • Name it : Path


Locate:

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\thunderbird.exe
  • Double click on 'Path' name to allow you to 'Edit String'.
  • Do not edit anything.
  • Copy all the 'Value Data' - highlight text, right click and select 'Copy'
  • click on 'Cancel' to close.

Locate

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\outlook.exe
  • In 'Name' column it will say Path.
  • Double click on 'Path' to open the Edit String.
  • Paste in the copied text - right click and select paste.
  • click on 'OK' to save


This should result in you having both a 'thunderbird.exe' (already installed) and a 'outlook.exe' (you newly created) in 'App Paths

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\outlook.exe
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\thunderbird.exe

When you select 'outlook.exe' it should look identical to when you select 'thunderbird.exe', so both are the same with the exception of the 'App Paths' name.

Your HP printer will look for App Paths\outlook.exe and find it, but it is tricked into using thunderbird program.
