When the program starts you may get a messages stating "The application has failed to start because its side-by-side configuration is incorrect".

This can be caused by an incorrect or corrupted theorderexchange.exe.config file. Open the event viewer as shown below.

Edit the theorderexchange.exe.config file and review the line mentioned in the message in the event viewer. Once corrected the program will run fine again.

This normally occurs when upgrading the theorderexchange.exe.config file.
