Re: Is FLEX v11.16 certified for Windows Server 2019?
There are multiple minor version releases of FlexNet Publisher from 11.16.0 to 11.16.6.
Here is list of all the releases - https://docs.flexera.com/eol/flexnet-publisher.htm
I checked the Release Notes for 11.16.0 and, no, Windows 2019 Server is not supported (likely due to timings and timeframes). Is another minor version used (e.g. 11.16.4)?
Also, I checked the current version, 11.17.0, and Windows 2019 Server is supported.
