How to detect Windows 64-bit platform with .NET?

Question

In a .NET 2.0 C# application I use the following code to detect the operating system platform:

string os_platform = System.Environment.OSVersion.Platform.ToS         


        

Answer 1

I use:

Dim drivelet As String = Application.StartupPath.ToString
If Directory.Exists(drivelet(0) & ":\Program Files (x86)") Then
    MsgBox("64bit")
Else
    MsgBox("32bit")
End if

This gets the path where your application is launched in case you have it installed in various places on the computer. Also, you could just do the general C:\ path since 99.9% of computers out there have Windows installed in C:\.
