We are trying to upgrade (in place) our ALM12.21 to 12.55 and are getting a strange error -- The installer seems to detect a previous instllation -- even though we just ran the 12.21 UNINSTALLER from Control Panel "Programs and Features".
We also made sure to delete all "left-over" folders from Program Files HPE (or HP) and from c:\ProgramData\HP (or HPE) \ALM -- but we left behind the conf and repository folders.
We even emptied the "recycle bin" and rebooted.
Why does it still sense a previous installation?
