When patching Java on win7x32 via managed software policy, I used the java-uninstaller.vbs script from here without issue. Worked great.
I tried modifying that script to the correct locations for the registry for 64bit windows7 - replaced all the lines that were "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\" and made them HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\" but the script didn't work to remove Java8u31.
I did find a powershell script that works, but I don't love the idea of having to disable/enable signing policy to run powershell scripts.
I tried this "Cleanup Script to Uninstall All Previous Versions of JRE" - on a machine with java 8 45 and java 8 31 - it uninstalls the 45 version instead of 31. Judging by this post (http://wpkg.org/Java) - it seems like Oracle did something unique with 31 ("Oracle included /i in the UninstallString.") which maybe is what I'm running into with some of the scripts not being able to remove it.
Adding /noreboot to this script works, but produces a 1605 error in the Symantec agent, I suppose when it hits an uninstall string for a version it doesn't have installed
Anyone have any suggestions? Someone out there in Symantec land must be scripting the uninstall of Java versions.
