{05/28/2024-14:43:59}The Installation needs admin permissions

Environment

XCOM r11.6 SP02 for Windows

XCOM r12.0 for Windows

Cause

The cause of the problem was related to the Java that is installed on their Windows system, which was not compatible with the XCOM installer.

Resolution

Double check if you have Oracle Java or OpenJava 8 installed on the Windows system. If so, then proceed with doing the following:

1. Open the CMD prompt as Administrator.

2. Change directory to where the XCOM installer executable is and issue command:

     XCOM_12_0_23053.exe LAX_VM <"c:\your\java\path\java.exe">

     where you would specify the complete Java 8 path on the command.

This will have the XCOM installer use Java 8 to perform the install. 

Additional Information

In order to determine what Java version the installer is using:

- Run the XCOM installer and press the CTRL key until you receive the failing message. This will run the installer in debug mode.

- Reviewed the debugger screen and was able to verify the Java being used.
