Twice.

I know this was some kind of issue in the last Release Candidates, e.g: Issue 24476

Thanks for reporting this. We will have an updated build that includes the VC runtime ASAP. In the meantime, you can fix this yourself by installing the VC redistributable from Microsoft: https://www.microsoft.com/en-us/download/details.aspx?id=48145

[msarahan]

Fixed in Python-3.5.0-1. Please update, and post back if you have further issues.

Closing then. @Ivoz, feel free to reopen this issue if you continue to have this problem.

It's can handle with the problem.

These DLLs are included with the msvc_runtime package, which the python package depends on. They are extracted into the \Library\bin folder. If you are updating an old installation, you may need to add that folder to PATH. Please let us know if this mechanism is not working for you.

@msarahan I'm on windows 7 and I added the Lib folder to my PATH and that fixed my problem, thank you.

I repeatedly encountered this problem when attempting to use the Anaconda3 2.4.0 64-bit installer on Windows 10 (without any other Python installation present). By "repeatedly" I mean that the error pops up several dozen times during the installation (which ultimately doesn't work properly as all the attempts to run the Python executable during the installation for things like menu icon creation, fail).

A temporary workaround, if you don't mind dealing with an older Python version, is to grab the 2.3.0 installer from the "zipped installers" link (which has old versions available).

[msarahan]

Yikes. One other solution is to install the Microsoft redistributable for VS 2015: https://www.microsoft.com/en-us/download/details.aspx?id=48145

Those are files that are extracted during installation, and should be in PATH during installation, but it appears something is going wrong on your system during installation, and those files aren't found. The Microsoft redistributable places them system-wide, so you should have no further problems.

Hey @msarahan - I just tried installing this on a friend's laptop today with the linked (2.4.0) installation of Anaconda. I'll do the workaround and post back if it fixes things.

[ahmadia]

I can't even install the C++ 2015 Redistributable on this laptop (just stuck on initializing), this is an unfortunate red flag for Python 3.5 installations :/

I had this same issue today: http://stackoverflow.com/questions/34363125/conda-python-environment-missing-dll-file-on-windows

Edit: the issue appears to have smoothed itself out.

Answer from Stack Overflow:

This issue is because something is going wrong with the msvc_runtime package. That package should contain these DLLs. Can you please verify the contents of your environment's root folder? These DLLs should live both in there, and in (prefix)/Library/bin.

One possible cause might be the wrong version of msvc_runtime: it should say [vc14] somewhere in conda list output for Python 3.5.x, and [vc10] for 3.4.x

One other cause might be that PATH is wrong after activation, and you're not picking up the DLLs correctly. Are you using cmd.exe or powershell? We don't support powershell yet - only cmd.exe is known to work. If using cmd.exe, can you post the output of echo %PATH% please?

i got the same error as i changed the path to Anaconda ,maybe it is helpful.
