Following the PI System Directory Installation process,
- I reran the PI-AF-Services_2017-R2A.exe
- At the Feature Selection, I unchecked all of the already installed components, and selected only the "PI System Directory - CTP"
- Installation completed.
What happened next was my PI System Explorer on the AF Server no longer worked, we tried a repair, no go.
From my client workstation PSE was connecting to AF and seeing PI tag data.
Accessed PI Vision, all displays were showing "No Data"
DO NOT DO THIS, Bad, Bad
Do not uncheck all the previous checked components
