Here's what I did:
instantclient-basic-nt-11.2.0.3.0.zip
, unzipped it, and put it in C:\Program Files\Oracle\instantclient_11_2
.Path
environment variable.ORACLE_HOME
holding this path as its value.cx_Oracle-5.1.2-11g.win32-py2.7.msi
.And on running import cx_Oracle
all I get is
Traceback (most recent call last):
File "<string>", line 2, in <module>
ImportError: DLL load failed: This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.
I obviously uninstalled / reinstalled cx_Oracle a couple of times but really nothing seems to help. Could anyone please provide a clue how to fix this?
UPDATE
I ran Dependency Walker and it comes up with a lot of trouble. However, the first missing .dll (msvcr80.dll) is actually present in C:\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.91_x-ww_0de56c07
.
OK, what finally solved the problem (not sure whether all steps are necessary and no idea why exactly this and only this worked so far):
