Next you just right click on opera.exe, set it to NT4 or 2000 compat mode and then you run it by double clicking on it, that's all.
Btw, when you install 7-zip it installs a shell extension in explorer with which you can extract archive, including self-extracting executables such as the Opera installer, without needing to launch 7-Zip itself, that's the context menu I was speaking about.
Also be aware that if you've got another version of opera somewhere else in a folder named opera they will both share the same settings, history etc... I f you want to have separate settings for different versions of Opera, make sure they are in folders that have different names as Opera will use, or create if none exist, a folder of the same name as the one containing the Opera.exe under C:\Windows\Application Data\Opera.
If you've got Opera in a folder named Opera, its settings will be stored in C:\Windows\Application Data\Opera
If you've got Opera in a folder named Opera 11.64, its settings will be stored in C:\Windows\Application Data\Opera 11.64
And so on.
