I struggled with your exact same problem when I moved to Linux. For the record, the reason why there isn’t a Program Files x86 is because the way that Linux stores programs is different from the way that Windows stores programs. Windows sorts its system files by programs, so that the configuration, launcher, and software files are all together. Linux sorts by file type, so that the configuration files of all programs are together, the launchers of all programs are together, etc.

What I’ve come to learn is, don’t bother trying to find your application in the folder. The best way to install things is through Discover (or whatever GUI software manager you’re using). If the program you want isn’t there, it’s basically a crapshoot whether installing from the internet will work or not
