Hi Edward. I have a the file *python27.lib* in C:\Python27\libs.
I still don't have a clue whats wrong. Could it be something with Visual C++ 2005 Express Edition? I am not sure the installation went correct, since when I do Windows Start button->Microsoft Windows SDK v7.1->Visual Studio Registration->Windows SDK Configuration Tool Change "Installed Windows SDK Versions:" from v7.1 to 8.0 I get an error: "Your system does not have Visual Studio 2005 or Visual Studio 2008 installed" Best Troels Emtekær Linnet 2013/5/11 Edward d'Auvergne <[email protected]> > Hi, > > We should be able to get to the bottom of the problem and make this > run.
