Remove CA iTechnology iGateway

CA iTechnology iGateway, which is installed with CA EEM, is a shared component that various CA Technologies products use. CA iTechnology iGateway is a web server that sends requests and receives replies using the http protocol.

CA iTechnology iGateway can be installed with other products also. If CA iTechnology iGateway exists on the computer where you are installing CA EEM, determine if it is 32-bit or 64-bit. If CA iTechnology iGateway and your CA EEM 12.51 server are both 32-bit or both 64-bit, no action is necessary. However, if the two products do not match (for example, one is 32-bit and the other is 64-bit), remove CA iTechnology iGateway. Then start the CA EEM installation. The correct version of CA iTechnology iGateway is installed when you complete the CA EEM installation.

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

Follow these steps:

  1. On the computer where you are installing CA EEM, remove CA iTechnology iGateway.

    Note: To uninstall CA iTechnology iGateway successfully, first uninstall all products that are dependent on CA iTechnology iGateway.

    1. Open the Control Panel (for example, click Start, Settings, Control Panel).
    2. Double-click Add or Remove Programs.
    3. Select CA iTechnology iGateway and click Remove.
  2. Remove the iGateway and iTechnology registry key folders from the following location: 
    HKEY_localmachine\SOFTWARE\ComputerAssociates\
  3. Delete the IGW_LOC environment variable.
    1. From the Start menu, right-click My Computer and select Properties.
    2. Click the Advanced tab.
    3. Click Environment Variables.
    4. Select IGW_LOC in the System variables list, click Delete, and click OK.
  4. Restart the computer.
  5. Install CA APM.
  6. When the CA APM installation is complete, reinstall the uninstalled components on the computer where CA EEM is installed.

Note: We do not recommend the installation of the CA APM components, except the CA MDB, on a 64-bit computer that hosts a 64-bit Oracle database server.
