Given that KB2999226 is for updating the Universal CRT (C RunTime) in Windows...

Quote from: https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows

The Windows 10 Universal CRT is a Windows operating system component that enables CRT functionality on the Windows operating system. This update allows Windows desktop applications that depend on the Windows 10 Universal CRT release to run on earlier Windows operating systems.

Microsoft Visual Studio 2015 creates a dependency on the Universal CRT when applications are built by using the Windows 10 Software Development Kit (SDK). You can install this update on earlier Windows operating systems to enable these applications to run correctly.

I would presume that having all the Visual C++ redists and VS2013 installed etc has probably installed this update for you. Given the choice of installing several gigs worth of VS and redists... and installing a simple update, I know which route most users would take Wink

(i saw this being linked elsewhere so i post this here)

are we sure these steps are required?
first of all you don't need Python to be installed and it doesn't have to be in your system folders. both of those DLLs are inside your Electrum install directory (C:\Program Files (x86)\Electrum) and the programs uses those to run.
second i am still not convinced we need the KB2999226 update! although i tell others they have to install it only because the website says you need to.

i have neither python installed nor this update an my Electrum runs fine!
i checked both system32 and sysWOW64 folders and there is no python dlls and also my updates don't have KB2999226 among them. however i have multiple .Net frameworks and Visual C++ Redistribution installed which were installed by Visual Studio 2013 that i use.

I solved!

These are the steps if anyone else experience similar problems:

1. I changed the permissions of my temp folder. Here is the step-by-step guide: https://superuser.com/questions/668820/google-drive-error-python27-dll
2. I copied python35.dll and python3.dll in system32 and sysWOW64 folder. I gotta thank this user: https://productforums.google.com/forum/#!topic/drive/qcHYkqeikLE
3. I installed the latest windows updates and rebooted.
4. Once reboteed, finally I can run both ELectrum and ElectonCash.

Thank you @tryninja for your help anyway!

As suggested, I'm trying to upgrade to Electrum-3.0.5 because of security issues.

But if I launch this upgraded version of Electrum, it failed to start and a pop-up opens saying : "Error Loading Python DLL".

What's the problem and how can I fix it?
