User fails to ensure that older JRE instances are removed while upgrading to JRE8u73/74 through silent installation on a 64-bit machine.

After executing the command "jre-8u74-windows-i586.exe /s REMOVEOUTOFDATEJRES=1" left with all the older instances of JREs not removed. Works fine on 32-bit machines.

The issue seems restricted to Windows Vista and Windows 2008. Attached screenshot depicting the versions that failed to uninstall. Also attached is the JRE log from the affected system.
