Cannot uninstall OpenEdge after AdminService has been stopped

Cannot uninstall OpenEdge after AdminService has been stopped
DLL in use prevents uninstalling OpenEdge

Uninstall process reports procfg.dll and environ.dll files are still in use.

AdminService was stopped before running the uninstall process.

Uninstalling OpenEdge licenses that include the AdminService.
AdminService was running immediately prior to the start of the uninstall process

If the needed files are still in use, they cannot be deleted by the uninstall process.

The uninstall is correctly reporting the files in use. These files are busy and therefore cannot be deleted. This has been identified as a timing issue between the AdminService properly shutting down and the Uninstall process starting. Typically it takes a while for the AdminService to shut down. Typically the AdminService  is not shutdown completely when the Services panel says it is.

Ensure that the AdminService has completely shutdown prior to running the Uninstall routine.

$ proadsv -query -verbose -port <listening port default 20931>
AdminServer not alive. (8543)
