We provided them with these remarks--from which the problem was resolved:
-
It seems there has been a Java update on the machine (maybe automatic) and at the same time it
uninstalled the old--previous version "C:\Program Files\Java\jre1.8.0_251".
So the environment variable XCOM_JAVA_HOME and XCOM.GLB parameter XCOM_JVM both
need to be updated accordingly--to point to the new Java version installation directory.
