Ik that this is old but, I have been working on setting this up for myself and I have made it to running the installer. I have all of the files that I need to open opera, but idk how to do that. If you have wine installed, you want to open the "uninstall wine apps" app and click on the install button. Add the setup .exe file to it and then it will run. For me, it would freeze then crash, and once it had crashed, I found the files.
