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.

Accepted Answer

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 ;-)
