Today, a user reported the following error, which occurred when attempting to load the extension.
The call to LoadLibrary(sosex) failed, Win32 error 0n14001 "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem." Please check your debugger configuration and/or network access.
The short answer to this is that I failed to include the VC9 redist. You can solve this problem by downloading the latest SOSEX zip file or by downloading the VC9 redist package from Microsoft. The link to the x64 package is also at the bottom of that page.
Here's how I got there, given error number 14001, in case somebody else sees a similar error message in their application. The description for error 14001 is "The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log for more detail." My search for an explanation of this error led me to this page on Junfeng Zhang's excellent blog. It was there that I learned that a missing CRT could cause this error.
