This confused me a bit. This is a portable app and as such is not "installable".thanks for the link to vivaldi 32-bit, mike.
seems to install okay,
When you refer to the "launcher" icon are you talking about the script named "LAUNCH" found inside the vivaldi-portable folder?i click on 'launcher' icon,
nothing
If you downloaded the "Vivaldi-portable32.tar.gz" file and extracted the contents you will see that the extracted directory is named Vivaldi-portable. Clicking on the icon for this directory should revealtwo executable files (scripts) named "LAUNCH" and "UpdatePepperflash" along with a subdirectory named "vivaldi".
Click on the file named "LAUNCH" this should cause the browser to start.
If it does not start try opening a terminal inside the folder using the right click context menu. Start "LAUNCH" from the terminal and see what happens.
