Is there an environment variable ProgramFilesx86 to locate C:\Program Files (x86) on a 64-bit Windows?
Although some of the MSDN documentation specifically mentions an environment variable ProgramFilesX96 member in the Environment.SpecialFolder Enumeration (http://msdn.microsoft.com/en-us/library/system.environment.specialfolder.as px ), it isn't shown by intellisense - Environment.GetFolderPath(System.Environment.SpecialFolder.ProgramFilesx86) and doesn't compile. Further, while I can use the Windows Run to expand %ProgramFiles(x86)% - "%ProgramFiles(x86)%\TextPad 5\TextPad.exe" -m -r "C:\Users\(some location)\MyApp.log" will work as desired, for example - if I want to start a process in code it doesn't expand the environment variable - MyProcess.StartInfo.Filename = "%ProgramFiles(x86)%\TextPad 5\TextPad.exe" (fails) I am using 3.5 Framework, and need to remain with this. Maybe in 4.0 the doco is correct and this works (have not tried) - or am I missing a few very obvious things? _____ Ian Thomas Victoria Park, Western Australia
