Plaso keeps telling me SQLite3 is too old

The Python installation bundles its own version of SQLite3 that is older than the version required by Plaso. Fix this by

  • Removing the old version of SQLite3:
C:\Python27\DLL\sqlite3.dll
C:\Python27\DLL\_sqlite3.pyd
C:\Python27\Lib\sqlite3\
  • Installing a newer version of SQLite3, if not already installed.

Not a valid Win32 application

When I load one of the Python modules I get:

ImportError: DLL load failed: %1 is not a valid Win32 application.

This means your Python interpreter (on Windows) cannot load a python module since the module is not a valid Win32 DLL file. One cause of this could be mismatch between a 64-bit Python and 32-bit build module (or vice versa).

Unable to find an entry point in DLL

When I try to import one of the Python-bindings or run the PyInstaller build I get:

ImportError: DLL load failed: The specified procedure could not be found. 

Make sure the DLL is built for the right WINAPI version, check the value of WINVER of your build.

setup.py and build errors

Cannot open input file 'kernel32.lib'

When I try to build one of the Python-bindings in 64-bit with Microsoft Visual Studio 2010 express I get:

fatal error LNK1181: cannot open input file 'kernel32.lib'

Make sure "Platform Toolset" is set to: "Windows7.1SDK"

Unable to find vcvarsall.bat

When running setup.py I get:

error: Unable to find vcvarsall.bat

Make sure the environment variable VS90COMNTOOLS is set, e.g. for Visual Studio 2010:

set VS90COMNTOOLS=%VS100COMNTOOLS%

Or set it to a path:

set VS90COMNTOOLS="C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\Tools\"

ValueError: [u'path'] when running setup.py

When running setup.py I get:

ValueError: [u'path']

Try running the command from the "Windows SDK 7.1" or "Visual Studio" Command Prompt.

I'm getting linker "unresolved externals" errors when running setup.py

If you're building a 64-bit version of a python binding Visual Studio 2010 express make sure to use "Windows SDK 7.1 Command Prompt".
