[IronPython] Installing IronPython 2.7b1 over 2.7a1

[Tony Meyer]

Hi,

Has anyone else had any issues with this?  When I try to do it I get
an error "A later version of IronPython 2.7 is already installed".
However, the only version of IronPython 2.7 that is installed is alpha
1 ("2.7.0.1"); 2.6 ("2.6.10920.0") is also installed.  I'm using the
msi installer from codeplex, which says it is "IronPython 2.7
(2.7.0709)".

I presume I can fix this by uninstalling a1 and then installing b1 - I
haven't had a chance to try that yet.

If no-one else has seen this, then I'm inclined to assume this is
something odd with my machine.  Otherwise I can open a bug.

Thanks,
Tony
