Thank you, Erel. The email I received has the download links, but no instructions. I downloaded the B4i IDE and ran the B4i.exe file. This automatically loaded all the new B4i program files to C:\Program Files (x86)\Anywhere Software\B4i directory. All looks well there.
I also downloaded the B4i Mac Builder. When I extracted the B4iBuildserver.zip file, it contained a Libs folder and an executable B4iBuildServer.jar file. I double-clicked this jar file and it extracted further so now it has folders for keys, Libs, and Uploaded projects, as well as B4iBuildServer.jar and config_example.txt files. These are all still located in my Downloads. Do I need to move these to another place or run another executable file that will set this up automatically?
