Front end and back end not compatible (must target same processor)

This error occurs when a .obj file is generated by a compiler front end (C1.dll) that targets one processor, such as x86, Itanium Processor Family (IPF), or x64, but is being read by a back end (C2.dll) that targets a different processor.

Ensure that you are using a matching front end and back end.
