[IronPython] I can't install the MSI for IP2.6 RC1

[Jonathan Hartley]

Hey there.

I can't install the IP2.6 RC1 msi. When the install is mostly done, it 
suddenly fails and rolls back. I can use the binary zip file instead of 
the msi, but wanted to ask if this is a problem anyone else was having.

At the end of the failed install and roll-back it produces a dialog:

   IromPython 2.6 Setup Wizard ended prematurely
   because of an error.

So I got a logfile of the install:

   msiexec /i IronPython-2.6.msi /log install.log

which produces verbose output, including:

...
Action 15:50:17: RollbackCleanup. Removing backup files
ExecNetFx:  Error 0x80070005: Command failed to execute.
ExecNetFx:  Error 0x80070005: failed to execute Ngen command:

MSI (c) (28:6C) [15:59:24:453]: Product: IronPython 2.6 -- Installation 
failed.


I'd like to try running the allegedly failing ngen command from a prompt:

   C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ngen.exe install 
"C:\Program Files\IronPython 2.6\Microsoft.Scripting.dll" /queue:1

but of course since the install rolls back, the file 
"Microsoft.Scripting.dll" no longer exists, so I can't. However, I can 
manually ngen *other* assemblies using a command exactly like this. The 
path to ngen.exe is correct, and the parameters to the command are 
correct, so I don't understand why this ngen might be failing.

Upon further investigation, trying to *un*install the IP2.0.2 msi also 
fails and does the same thing. I currently don't know how I'm going to 
get that uninstalled except by some sort of 'rm -rf' style extreme 
prejudice.

Install and uninstall of other programs seems to work ok.

Is it just me? Thoughts very welcome.

   Jonathan
