I just installed callmanager patch ES42. In the readme file, it said the AdministrativeReportingTool.exe file should be upgraded to 4.1(0.41) , But I check the file version, it is still 2.11.15.0
If you have CDR Analysis and Reporting (CAR), formerly known as Administrative Reporting Tool (ART), running on your system before upgrading to Cisco CallManager Release 3.2, the upgrade process automatically upgrades CAR. If you are installing Cisco CallManager for the first time, you must install the CAR plugin.
You can install plugins from callmanager Administration page > Application>install plugin.
