Follow these steps to install ImproveBuild RBS on a computer that will be used as an RBS Workstation:
Download the setup files using the link in the email from ImproveBuild Sales\Support.
Unzip the IRBS_Client.zip file.
Run the IRBS_Client.exe in the newly uncompressed IRBS_Client folder.
Follow the installation prompts (it is recommended that the defaults are used).
After all the files have been installed, copy the appconfig.xml file from the "RBS Server" location (normally \\<ServerName>\IRBS_Server where <ServerName> is the computer that has the RBS Server components installed).
