I install both JREs 1.8.0_121 (32 and 64bit) on a Win7 Pro 64bit machine in unattended mode.
The switches I use are: /passive /log c:\logs\java8\java8_msi.log REBOOT=Disable NOSTARTMENU=Enable REMOVEOLDERJRES=1 SPONSORS=Disable WEB_ANALYTICS=Disable AUTO_UPDATE=Disable
First the JRE 64bit installation works fine.
But the following 32bit installation with the REMOVEOLDERJRES=1-Switch surprisingly removes the key and values of the 64bit JRE in the registry in HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall but leaves the files in C:\Program Files\Java\JRE1.8.0_121.
If I don't use the REMOVEOLDERJRES=1-Switch the 64bit-Installation is left as it is (and it should be so with the REMOVEOLDERJRES=1 as ist was in the previous updates).
When I install the 32bit JRE following the 64bit JRE-installation der Registry-Key of the 32bit installation is automatically deleted.
Does anybody have this behaviour too?
Is it a bug or a feature? ;-)
