program files dir with with Windows 7 using .net

I'm testing some of my software to make sure it works with Windows 7. My current software uses a command like:

Process.Start("C:\Program Files\myapp\myapp.exe", "test", pwd, "mydomain")

I can I code this to work with both XP and Windows 7. Currently it fails on Windows 7 because it's looking in the x86 folder.

In .NET 4.0 you can do this:

Environment.GetFolderPath(Environment.SpecialFolder.ProgramFilesX86)

In previous versions:
VS2008-2010

Dim path As String = If(Environment.GetEnvironmentVariable("ProgramFiles(x86)"), Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles))

Open in new window

VS2005

Dim path As String = If(Environment.GetEnvironmentVariable("ProgramFiles(x86)") Is Nothing, _
                                Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles), _
                                Environment.GetEnvironmentVariable("ProgramFiles(x86)"))

well i thought i should share this as well, here is the code to tell you if you are running your app on 64 bit windows or not:-

probably then you can decide to look for in program files(86) folder for you app.exe

Another thing to keep in mind is that Win 7 wont allow your program to access program files folder unless its running in admin mode.

This worked great.

That will work as long as the user hasn't got Program Files folder set up on an alternate drive, like D:
