There is an issue with VC when configuring via vcfg.

The identity of the created agent is not what vc is expecting. VC expects an identity of platform.historian, however vcfg doesn't default to an identity so it is installed with identity sqlhistorianagent-4.0.0_1.

There is an issue with setuptools 40 in python 3.9. This has been dealt with in #2780

The issue with vcfg has been dealt with and will be in the soon to be released 8.1.1 #2782
