Windows 7 / 64-bit / 4 Gb Ram / Intel i5 processor.

This seems to have been discussed intermittently in the past, but none of the previous answers fixed my problem.

I installed 3.5, and when I tried running it (both from the Windows cmd line and from the python cmd line) I received the error

"The prodecure entry point strncmp could not be located in the dynamic link library VCRRUNTIME140.dll"

I installed 2.7.12 and received the same error.

I then uninstalled 2.7.12 and installed 2.7.11 and found that running this worked from the python cmd line but not from the windows cmd line.

I then tried installing 3.5.11 and found vcruntime140.dll in the python directory. I copied this to the python 2.7 folder, uninstalled 3.5.11 (and 3.5.12 – after realising that the original installation didn’t seem to have completed successfully anyway, despite saying it had!), and now when I run python from both the windows cmd line and python cmd line it seems to work.
