A DESCRIPTION OF THE PROBLEM :
Using the following parameters for JDK 8u40 works perfectly.

start /w jdk-8u40-windows-x64.exe INSTALL_SILENT=Enable /L C:\Java\jdk.log ADDLOCAL="ToolsFeature,SourceFeature" "INSTALLDIR=c:\Java\Jdk8" STATIC=0

It installs without touching the 8u40/8u45 jre 32/64 bit installations that is present on the machine.

Now with the latest 8u45 theres something going on... Observe these two install commands are identical except the filenames are different. This one below dows not behave as expected.

start /w jdk-8u45-windows-x64.exe INSTALL_SILENT=Enable /L C:\Java\jdk.log ADDLOCAL="ToolsFeature,SourceFeature" "INSTALLDIR=c:\Java\Jdk8" STATIC=0
