CVTRES Fatal Error CVT1100

duplicate resource — type:type, name:name, language:language, flags:flags, size:size

The given resource was specified more than once.

You can get this error if the linker is creating a type library and you did not specify /TLBID and a resource in your project already uses 1. In this case, specify /TLBID and specify another number up to 65535.
