How to set Opera 12 as the mailto url protocol Win 8

  • Using http://www.nirsoft.net/utils/file_types_manager.html you can access and change the url protocol. How can I change that to Opera 12.17? I have it installed in e:\opera as a usb install and running Win 8.

    Here's what's currently in my url protocol...
    %SystemRoot%\system32\url.dll,2

  • I have it installed in e:\opera as a usb install and running Win 8.

    You're not supposed to set a USB installation as the default browser. The USB install purposely doesn't write the necessary keys to the registry to make it the default.

    However:

    Load this page in Opera 12 and take a look at post #3 (single user installation example).

    Launch the Opera installer as an admin (launch a command prompt as an admin and type the command in the prompt for example) with all those command line options where /installfolder "e:\epera" is in the command. If e is a removable drive, you'll have to do the same thing on other computers. Just note that if the drive isn't 'e' on the other computers, you'll have to change the letter in the /installfolder argument when you run the command on those computers.

    Then, you should be able to set the installation as the default in its preferences if it's not already the default. If you don't want it as the default browser too, uncheck that in Opera's preferences and or let the browse you want reclaim itself as the default.

    Not sure about that program.

  • Thanks for the response Burnout.

    But just to clarify. I didn't need to set Opera 12.17 as the default browser on my system. What I needed was the the mailto url protocol format.

    Let me ask this differently. Before Opera 15 (Chrome Engine) came out was there a command line to start opera right into compose mail mode. Ergo, mailto?

    Does that make sense?

  • Does that make sense?

    Yes. The instructions I gave you are basically what you need to do just so you can set up the mailto association. However, if you want to bypass all that and do it the quick and dirty way, edit "HKEY_CURRENT_USER\Software\Classes\mailto\shell\open\command" and "HKEY_CLASSES_ROOT\mailto\shell\open\command" in the registry. For example, the value of the "(Default)" strings in each should be:

    "C:\Program Files (x86)\Opera\opera.exe" "%1"

  • Well ... each should be the path to his Opera install, which was on his E drive somewhere.

  • Well ... each should be the path to his Opera install

    Indeed.
