,→Install JRE with msi without removing old version in a mixed 32-bit/64-bit environment: Update to patch 26, use variables for easy updating, clarify MSI extraction procedure
===Install JRE with msi without removing old version in a mixed 32-bit/64-bit environment===
On 64-bit hosts installing the exe doesn't work.jre-6u17-windows-i586.exe is a 32bit app containing a msi, a cab and some other files.On a 32-bit host it unpacks in in c:\Windows\system32\config\systemprofile\AppData\LocalLow\Sun\Java\jre1.6.0_17\.On a 64-bit host it unpacks in c:\Windows\SysWOW64\config\systemprofile\AppData\LocalLow\Sun\Java\jre1.6.0_17\.The the silent install on a 64-bit host is still looking for the msi in the *System32* directory, so the best thing to do is to install the msi package.
You should install both 32-bit and 64-bit java on 64-bit machines if you want a 32-bit browser being able to use java.
