SOLVED: replisapi.dll class failed 0x80040154

Upgraded my SQL server from 2016 to 2017, and after the udpate, my replication clients weren't synchronizing anymore. Ran the replisapi.dll?diag and was getting a failed on replisapi.dll class, with error message 0x80040154.

Turns out all I have to do was to rerun a regsvr32 replisapi.dll with the new file from my SQL COM folder, reboot and was back on track.

Hopefully this solves the problem for someone else.
