Thank you so much for the quick response!!
>>no other ArcGIS Components running on the machine
I am not sure what is other ArcGIS Components mean. I checked Windows' task manager and stopped services that service names start with ArcGIS and SOC.exe. Is there another way to ensure all ArcGIS components are stopped?
>>Also are you running the script with the service stopped?
Yes, that I made sure.
I found the log4j-core-2.11.1.jar.bak file. I am just mentioning this since I have no clue regarding the issue.
I very much appreciate your assistance.
Thank you,
Makiko
