While I try to load the arcpy module in arcGIS 10.3.1 I get the following error message:

    Runtime error

  • Have you installed other version of python instead of one that comes with arcmap? – SIslam Jun 1 '16 at 10:31
  • Yes I have install the stand alone version of python 2.7.11 – Dimitris Kasabalis Jun 1 '16 at 10:35

    Please edit the question to specify the installation prh used for Pythom 2.7. I'd recommend uninstall/reinstall, making sure there are no spaces in the PATH. – Vince Jun 1 '16 at 10:35
  • What was in the code snippet that you ran to get that error? – PolyGeo Jun 1 '16 at 10:49

    @GISFORESTRY Please, answer you own question, so other people can handle this problem too. – Mr. Che Jun 1 '16 at 11:09

Finally I manage to fix this problem by unistalling the standalone version of python 2.7.11, and now everything works great.

    This is exactly the problem, and it is also how you can reproduce it -- run the Visual Studio 2017 installer and telling it to install 32-bit Python 2.7 will cause the problem. VS installed a copy of Python into C:\Python27. When I ran "Field Calculate" in ArcMap 10.5, it started using C:\Python27\python.exe instead of the version installed by ESRI's installer which is in "C:\Python27\ArcGIS10.5". (IMO this is an ESRI bug, they should check for their own version FIRST.) Simply reinstalling ArcGIS Desktop WILL NOT fix this problem unless it removes C:\Python\python.exe – brian h wilson Jan 25 '18 at 23:55
