So I have come to realize that the problem must indeed be my virus software.

However, I need that virus software on the PC. If I reinstall EB, will they be able to coexist peacfully? What changes can I make to my security setting to make sure that they will?

Anyways, I've been planning to put the force diplomacy mod on there for my AAR. Also, I've wanted to try out EB on BI instead of vanilla, so I'll just uninstall>reinstall and redo it all.

i just downloaded eb 1.1 from the official site and the setup application runs but something is wrong with it and when its finished it does not run eb it runs vanilla rome still anybody else with the same problem?
About 75% of users have that problem.

But I suppose it could be for a variety of reasons, some of which depend on your PC and settings.

However, since it's going to vanilla, it would seem that the PC is not being routed into the EB folder upon startup, which means that although you've installed EB, it's not really connecting with vanilla like it needs to to work.

Did you make sure to install EB outside of Program files?

Also, you should install EB 1.2, which is like a huge patch for 1.1
