Hey. This Post is a bit older, but i found a solution. I´ve made a Registry-file, that allows Windows to use, Opera Portable in this Case, as the default Browser. If you want me to share this file, just tell me here and i post it.
If you share it, you make me a nice Christmas present
I dont know, if every of these lines is needed. The only thing i know is, that it works perfectly.
Just create an xyz.cmd file whereever your launcher.exe for opera portable is, paste in the following text and start the cmd file with
admin rights. Thats it.
If it doesnt work, you should check, if Opera Portable is set as you default web browser inside the windows settings
The Code:
