ASIDE: Anyone out there got access to the Wiki?  This has been solved several
times, it would be nice if we didn't need to keep reposting it here.  Thanks!

Back to the issue:  This problem has occurred many-many-many-many times.  The
problem is not only that the DLLs are missing, but that they're not ordinary
DLLs, so you can't just copy them over.  They are part of Microsoft's new
side-by-side system (C:\WINDOWS\WinSxS) for managing the different versions
of DLLs a system needs.  It's a decent solution, but it's taking time for
everyone to understand how to use it.

The problem itself is caused by Python 2.6, which now requires the Microsoft
Visual C 9.0 assembly.  Py2exe doesn't understand this, and doesn't grab the
assembly automatically.  But if you copy the assembly along side your exe
manually, then it will work just fine.  You do this by creating a dir named
"Microsoft.VC90.CRT", then placing these files inside:

msvcm90.dll
msvcp90.dll
msvcr90.dll
Microsoft.VC90.CRT.manifest

You can find the assembly in C:\WINDOWS\WinSxS, though it might be in your
Python 2.6 dir instead.  The DLLs will be in a dir named like
"x86_Microsoft.VC90.CRT_*".  The rest of the name varies based on version
number.  The manifest file is in the Manifests dir, with a name matching the
full name of the dir where you found the DLLs.  Copy out the manifest and
rename it as above.

You can tweak your setup.py to include these files automatically.  You'll
need something like this:

    datafiles = [
    	("Microsoft.VC90.CRT", [
		"misc/Microsoft.VC90.CRT/msvcp90.dll",
		"misc/Microsoft.VC90.CRT/msvcr90.dll",
		"misc/Microsoft.VC90.CRT/msvcm90.dll",
		"misc/Microsoft.VC90.CRT/Microsoft.VC90.CRT.manifest"]),
    ] 

The other solution is to download Microsoft's installer for the above, which
will permanently install these DLLs into the Windows dir.  You won't need to
include them in your setup.py, but every user will need to run this if they
don't have Python 2.6 installed.

Note that the license for this is a little weird; it's not clear whether
you're allowed to redistribute the DLLs (or even the installer) unless you
own Microsoft Visual C.
