If you try to start proxy 0.8.2 in Windows, and you receive this error:
The application has failed to start because its side-by-side configuration is incorrect.
Then you need to install the Microsoft Visual C++ runtime libraries (per the 0.8.2 changelogs). Here is the snippet from the changelogs (it just doesn’t mention the error):
The Microsoft Visual C++ runtime libraries are now a requirement for running MySQL Proxy. Users that do not have these libraries must download and install the Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package MFC Security Update. For the current Proxy version, use the following link to obtain the package:
And here is where you can download the Visual C++ runtime libraries:
Download the proper file for your OS: 32-bit, 64-bit, or IA-64 and install it. Installation is simple, quick, and no restart is required.
After that, restart proxy. The error should not arise and the proxy should start up normally.
However, should you still experience this error even after installing the Visual C++ runtime libs, then perhaps add some info to this bug:
Hope this helps anyone out there searching google for this specific error.
