It Does:

1. Handle install and uninstall of: x64 and x86, JRE of Java 1.6.0.10 until 1.8.0.11, JDK of Java 1.7.0.0 until 1.8.0.11
2. Installation of Java 8
3. Add the JCE Patch to every Java installation; see: JCE Documentation
4. Use the check_msi-exitcode script from “Der-Matze”: check_msi-exitcode

It Does NOT:

1. Uninstall Java versions older then 1.6.0.10, because in update 10 was a new installer dropped which uses an other schema of GUID´s at the Windows Registry
2. Uninstall Java JDK`s older then 1.7.0.0

The package includes the MSI installer for the JRE and JDK x86, because if you want to install Java JRE/JDK x86 on a x64 System the EXE installer will “crash” if it was called in a SYSTEM user context. Calling it by hand will work and my package is designed to manage both cases.

It “crashes” in a SYSTEM user environment, because the x86 installer of Java would exteact a MSI package on a x86 System into “C:\Windows\System32\config\systemprofile\AppData\LocalLow\Sun\Java” and call a MSI file and will install Java.
But on a x64 System the Java installer want to extract the MSI package into the same directory. At this point Windows (x64) redirect the request to “C:\Windows\SysWOW64\config\systemprofile\AppData\LocalLow\Sun\Java”. The x86 Java installer does NOT notice the important redirect and still try to call the MSI file and explode with a, File not found, exeption.

There is no error-reporting or handling by the Java (EXE) installer done, but msiexec.exe does report an 1619 (PACKAGE_OPEN_FAILED) exitcode.

This happends only on x64 System`s. My package will ever prefer of using the EXE installer, the MSI files were only called in a fallback case!
