Issue uninstalling old ArcGIS Enterprise and running Enterprise Builder

tigerwoulds

I am trying to install ArcGIS Enterprise 10.9.1 on a Windows AWS machine using Enterprise Builder. This machine previously had 10.8.1 installed manually without Enterprise Builder. 

I have followed this guidance here to uninstall all components of 10.8.1: How To: Perform a clean uninstallation of ArcGIS Enterprise base deployment components (esri.com)

When I try to run the Enterprise Builder installer I get this error:

The ArcGIS Server, Portal, Data Store and 2 Web Adaptors have been uninstalled and I verified there are no windows services running for any of those pieces. Any other common places to check for 'ghost' files?

Solved by silently uninstalling the Data Store and Server pieces. That removed the remnants/ghost files and allowed me to proceed with the Enterprise Builder install.
