@lillollo said in Opera portable transfer old profile troubles:
it does this 3 or 4 times in a row
Yes. Opera has an autorestart after crash feature that it tries a few times and then gives up.
First thing I would do is rename the "profile" folder to "profile old" and try to start Opera. If it doesn't crash any longer, you know it's in your profile folder. When done testing, you can delete the new "profile" folder and rename "profile old" back to "profile".
Another thing you can do is try to start Opera in safe mode. In a command prompt:
cd "path to your Opera folder"
and then:
launcher --disable-gpu --disable-extensions
What's that do?
On a side note, hit Windows key + r, type control folders and press enter to load Explorer's folder options. On the "View" tab, uncheck "hide extensions for known file types". That way you can see file extensions for Opera's files.
