A new installation also fails stating that the instance exists on the Drive / Folder that was removed by mistake.

Component : DOLLAR UNIVERSE

OS: Windows

Cause

The Dollar Universe 6  setup reads from the Registry the existing Installations.

Resolution

Remove the installation from the Registry after having deleted the Dollar Universe Services.

To do so, launch regedit and  then delete or rename the Instance_COMPANY_NODE folder that appears in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ORSYP S.A.\Dollar Universe\ 

Then attempt a new installation, this time it should not detect any more that old corrupted Instance.
