Answer 1

I used the CurrentVersion\Installer\Folders registry key. Just pass in the product name.

private string GetAppPath(string productName)
    {
        const string foldersPath = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Folders";
        var baseKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64);

        var subKey = baseKey.OpenSubKey(foldersPath);
        if (subKey == null)
        {
            baseKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32);
            subKey = baseKey.OpenSubKey(foldersPath);
        }
        return subKey != null ? subKey.GetValueNames().FirstOrDefault(kv => kv.Contains(productName)) : "ERROR";          
    }
