A few months ago I started having problems when I wanted to update my version of opera. the update was available but when I clicked on it, it just restarted the browser and continued with the old version.
I posted the problem in this forum and they told me to try with the installer. so I did and it was impossible. I had to reinstall manually. Now after months the same thing is happening again. I tried to update from operasetup and it didn't work.
now every time I try to open the program I get this.
I already know in advance (because it is not the first time it happens to me) that I have to do the manual uninstallation, since I cannot reinstall or uninstall.
What I do not remember is how to do it.
