Please try the following:

if (Environment.OSVersion.VersionString.Contains("Windows 7") && Environment.Is64BitOperatingSystem)
{
    // Windows 7, 64-bit
}

Open in new window


System.Environment.OSVersion
http://msdn.microsoft.com/en-us/library/system.environment.osversion.aspx

System.Environment.Is64BitOperatingSystem
http://msdn.microsoft.com/en-us/library/system.environment.is64bitoperatingsystem.aspx

System.Environment.Is64BitProcess

That seems logical... what I need to know is if a 32-bit program (Firebird) is installed in Program Files or Program Files (x86), without coding a whole bunch of statements.  Is this the best way to accomplish that?

Hello
I would check this by looking in the registry.
In order to do that, you will have to know the know the exact application name (display name), like it whows in "Add/Remove Programs" (or "Programs and Features").

Here is a very basic and simple code example for locating the application "Spotify" (which I happen to have installed on my computer):

RegistryKey regKey = null;
String keyPath = null;
String appName = null;
String appPath = null;

appName = "Spotify";
keyPath = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\\" + appName;
regKey = Registry.LocalMachine.OpenSubKey(keyPath);

if (keyPath != null)
    appPath = regKey.GetValue("InstallLocation") as String;     // Cast to String in case of NULL value

Open in new window

You will now have the install location for the application.
In this example, this is "C:\Program Files (x86)\Spotify"

From this, you will be able to check this with the environment variable for "Program Files".
Environment.SpecialFolder.ProgramFiles. Many ways to go from here.

There is also more information to get (like DisplayName, DisplayVersion, URLInfoAbout, URLUpdateInfo, HelpLink, Publisher,  Comments)

Hope it helped :-)
