In our office when I make a change in a project file it marks the product version as 7.10.3077 whereas for the other guy in the office it would be set to 7.10.6030. Any idea where this difference comes from?
Do you mean the product version within the project file itself or the product version of the assembly you're building? If you are referring to the project file itself then it sounds like you are running the release version of VS2003 whereas the other guy is running SP1. A hotfix might also have modified the product version.
