Pay attention that Setup links to the last updated one 64 or 32bit

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Cygwin\Setup
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Cygwin\Setup

Installations report all if more are installed (borderline case, maybe)

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Cygwin\Installations
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Cygwin\Installations

both version 32 and 64 bit are reported on

Computer\HKEY_CURRENT_USER\Software\Cygwin\Installations
