Greetings, hopefully, you can understand English. With the power invested in my by Google Translate, I will attempt to answer your questions. AdwCleaner doesn't install anything since it is a standalone software. If you haven't had any malware or there are no files that need to be quarantined/stored, there will be no reason to create a folder in C disk. Try doing a scan once. It should appear afterward if you ask for debug logs.
