Howto: Get the right version for your OS

There's been a number of posts to the support forum that appear to be a result of confusion regarding which version of Express-C to download and install. Here's a quick howto for you to get the right version.

1) Windows or Linux
- simple enough: are you running Redmond or Penguin? Express-C supports both, but you'll definitely need to know this one

2) 32 bit or 64 bit
- on Linux, run the 'uname -i' command. This command queries the system as to what platform is running, and should return one of the following:
  • 'i386' => 32-bit
  • 'x86_64' => AMD 64-bit
  • 'IA64' => Intel 64-bit
  • 'PPC64' => Power PC 64-bit
- on Windows, click "Start" and then "Run". In the dialog box, type winmsd.exe and click "OK". In the "System Information" window, locate the "System Type" record in the right hand pane. It should be one of the following:
  • 'X86-based PC' => 32-bit
  • 'Itanium-based PC' => 64-bit

3) 2.4 or 2.6 kernel (Linux only)
- to get the right kernel level download, run the 'uname -r' command from a terminal. This will return the full kernel level, though you only need to note whether it starts with '2.4' or '2.6'.

So now you have your operating system, your processor level, and kernel level for linux. The only thing you have to remember is that you cannot run the 64-bit version on a 32-bit processor.
