How to find the list of installation keys for the Opera browser?

Question

Opera

You need to install via invoke-command Opera_setup.exe
The problem is that the script hangs stupidly. Installed by hand with no problem.
The /i /s switches don't help.
I also visited the keys / alluser / setdefaultbrowser / launchopera - the effect is the same.
I did not find the necessary information in the documentation on the Opera website and forum (or I did not search correctly).
Tell me how to find out (where to find) the necessary arguments or already use orca to search for them (or write the answer file).
Thanks in advance.
