XCOM Windows 11.6 SP3 and OpenJDK 1.8 345


There are compatibility issues between certain versions of InstallAnywhere (used for the XCOM installation), java.exe and Windows versions.
In particular this combination can cause problems but other/earlier versions of Windows may also encounter similar problems:
Windows Server 2022 21H2 and XCOM Windows 11.6 SP3 and OpenJDK 1.8 345


XCOM for Windows 11.6 SP03 and patches no longer distribute Oracle Java with the installer and Java needs to be installed by the user.
The installer searches for the file java.exe using first the directories contained the PATH environment variable and then the Windows Registry.

1. Verify the default version of Java installed on the system (found first in the PATH) by issuing the following command:
    C:\>java.exe -version
    java version "1.8.0_291"
    Java(TM) SE Runtime Environment (build 1.8.0_291-b09)
    Java HotSpot(TM) 64-Bit Server VM (build 25.291-b09, mixed mode)

NOTE: You may need to download and install a different version of Java should you not have one already installed.

2. If you have a different version of Java Runtime Environment (JRE) installed in directory JRE_INSTALL_DIR,  then use the following command to perform the install (double quotes required if JRE_INSTALL_DIR contains spaces):
   C:\>XCOM.exe LAX_VM "JRE_INSTALL_DIR\bin\java.exe"
This will force the InstallAnywhere to use that specific Java version rather than the default version.

3. To uninstall, use command:
  C:\>C:\Program Files\CA\XCOM>Uninstaller_R116SP03\Uninstaller.exe LAX_VM "JRE_INSTALL_DIR\bin\java.exe"
