Could not find an editor for H (.) files

When creating a new signature in Outlook 2003 on Vista I get the following error when I press the Advanced Edit… button;

“Could not find an editor for H (.) files”

How do I correct this?

Signatures buttonThis seems to be quite a common issue but the solution is easy.

  1. Open Control Panel and choose Internet Options.
  2. Here select the Programs tab.
  3. Change your default HTML editor to another program in the list.
  4. Press Apply.
  5. Change it back to whatever you want your default HTML editor to be.
  6. Press OK.

Now when you press the Advanced Editor button when creating your signature, the error should be gone.
