Remove CA iTechnology iGateway

Before you install CA EEM on 64-bit computers, verify that CA Technologies iTechnology iGateway (32-bit and 64-bit) is not installed on the computer where you are installing CA EEM. This verification task applies to all installation modes (standard, custom, and demonstration). If CA Technologies iTechnology iGateway is already installed, remove the component before you begin the CA EEM installation. CA Technologies iTechnology iGateway (32-bit) is installed when you complete a successful CA EEM installation.

Note: Various CA Technologies products or components install the 64-bit version of CA Technologies iTechnology iGateway, including the 64-bit CA Technologies eTrustITM agent.
