That explains it. It’s time to upgrade. 8.2 has been out of support for almost 2 years - [Announce] Tivoli Endpoint Manager Platform 8.1 and 8.2 End of Support
I’m not sure 8.2 even support for a 64-bit client. Sure there are cases for running older clients on older machines (where a new client may not be available, for winxp for example), but a Win Server 2012 R2 should really be running a 9.x client.
