When running python26 under windows OS (64bits)..... I have got errors like:
import win32api\" error in Python 2.6: pywintypes26.dll
or
I could fix this situation by removing all installed Python3.4 versions (had forgotten to uninstall 3.4.1 before installing 3.4.2), deleting C:\Python34 and after installing Python 3.4.2 pywin32-219.win32-py34.exe could be installed and called without problems. So, copying around DLLs should NOT be necessary!
