When I install MySQL Workbench 6.3 into my Windows 8.1, I encounter the following System Error :

I already tried to redownload and reinstall the program but this error dialog appears every time. How to fix this?


I am getting the same error and I installed using MSI.

Downloaded the VC redist packages for x64 and it fixed the issue:

Visual C++ Redistributable Packages for Visual Studio 2013

Strange that the error message has python.exe as it's title.

  • You must also download VC redist packages for x86 in order for Workbench to work well. – Alvaro Soares Dec 28 '16 at 14:50

You probably "installed" from the zip package, which does not do any validation of the available prerequisites for MySQL Workbench. I strongly recommend to use the Windows Installer (or at least the msi) which check if the VC++ 2013 runtime is installed (which includes the mentioned DLL). The installer also allows for easy upgrades and helps you with the setup.


I had the same problem and I found the missing dll in C:\Windows\SysWOW64 folder. Just copy it to System32 and was fixed.

If you still have the @MikeW error with python.exe is because you have a 32bits version of one and the 64bits of the other (Python and Workbench).
