Also, the docs for the .NET 3.5 version of the SpecialFolder enumeration don't have the ProgramFilesX86 entry. I guess they added it in .NET 4.0.
Out of interest, what happens if you do this: Environment.GetFolderPath((System.Environment.SpecialFolder)42) Where 42 is the value assigned to ProgramFilesX86. I'm just wondering if the value is important or if it goes to a giant switch statement.<http://codermike.com> On Wed, Feb 8, 2012 at 4:46 PM, Michael Minutillo < michael.minuti...@gmail.com> wrote: > Hi Ian, > > If all you want to do is start a process in code you can use the > Environment.ExpandEnvironmentVariables(..) method to do it for you: > > Environment.ExpandEnvironmentVariables("%ProgramFiles(x86)%\\TextPad > 5\\TextPad.exe") > > Returns > > C:\Program Files (x86)\TextPad 5\TextPad.exe > > on my machine.
