How to check with C# where a program is installed

Question

I need to check where a program is installed by program name (name that appears in Add or Remove Programs). What is the best way to that so that it'd work fine for all languages.

Answer 1

Take a look into the registry at

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

Just iterate over all subkeys and take a look into the values DisplayName and InstallLocation. Here you'll find the infos you want and much more ;-)
