(I also asked this on StackOverflow -
mode-on-64bit-machine-even-when-running-ipy64-exe - have copy pasted
I am sure I am missing something simple but unfortunately a lot
of searching hasn't thrown up what it is..
I am running Windows 7 64-bit (I verified this by looking at Control
Panel > All Control Panel Items > System and seeing that it says 64-bit
I have IronPython 2.7.3 installed from here
This has created the following shortcut (with no corresponding shortcut
in C:\Program Files\IronPython 2.7...):
"C:\Program Files (x86)\IronPython 2.7\ipy64.exe"
If I run this, I get this prompt:
"c:\Projects>"C:\Program Files (x86)\IronPython 2.7\ipy64.exe"
IronPython 2.7.3 (22.214.171.124) on .NET 4.0.30319.296 (32-bit)
The docs from an older version of IronPython (2.6)
<http://ironpython.codeplex.com/releases/view/27350> say that:
"A very visible new feature added to this release is that ipy.exe is now
strictly a 32-bit only assembly. That is, it gets executed as a 32-bit
CLR process on both x86 and x64 operating systems. ipy64.exe, despite
what its name might imply, is a platform agnostic assembly matching the
old behavior of ipy.exe in the sense that it gets executed as a 32-bit
process on 32-bit OSes and 64-bit on 64-bit OSes."
>From this, I infer that ipy64 should have started as a 64 bit process,
but that's not what shows in the prompt.
Any ideas what I am doing wrong? Thanks in advance..
Edited to add: I have also tried running the following in the IronPython
shell, which I found from another question on this site, to check
whether the OS is 64 bit
>>> import System
... but then I ran the following which indicates that IronPython really
is running in 32 bit mode.
>>> import System
I have tested that I have 64-bit .NET installed by creating a console
application in Visual Studio with the line
Console.WriteLn(System.IntPtr.Size) and verifying that the output is
