Solution 1

Python 2.5 links against msvcr71 just like 2.4. Versions 2.6 and 2.7 link against msvcr90 which is the VS2008 runtime. In fact versions 3.0, 3.1 and 3.2 also link against msvcr90.

The msvcr90 redistributable is here: http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=29

Solution 3

If you're building packages (not sure about building Python itself), this new compiler may do the trick:

Microsoft Visual C++ Compiler for Python 2.7

msvcr71.dll, msvcp72.dll Different versions?

[Michael Allan Jackson]

"If you are looking for a file that ends with a "P" such as msvcp71.dll, this indicates that your file was compiled against a C++ runtime (as opposed to a C runtime), " I am curious if one or other is correct, but you find people making reference to both.

[metamatt]

The C++ runtime is additive; it's not a question of one or the other. msvcrXX.dll is the dynamically-linked version of the C runtime library. msvcpXX.dll is the dynamically-linked version of the C++ runtime library. A normal C application (that wasn't statically linked with the C runtime library) will need msvcrXX.dll (XX depending on the version of the compiler you used). A normal C++ application will need both msvcrXX.dll and msvcpXX.dll.
