A friend bought a new laptop and of course I am the sysadmin.
After updating Java (JRE, the web plugin stuff, not JDK), I checked by "java -version" and I saw I still have 1.6.0_17 in stead of update 24.
Afterwards I noticed that I have two copies of java, one 32 bit and one 64 bit (it is a 64 bit Windows 7 system).
The 32 bit version is 1.6.0_24.
So how to update the 64 bit version?
(and why doesn't the installer do this automatically?)
I tried running the 64 bit version of jucheck.exe .... and it started installing, but the claims, this version is already installed. But it allows a reinstallation, and I chose that. It installed, but afterwards java.exe still claims version 1.6.0_17
Uninstall the 64 bit version? (if there is a separate item in Control Panel for it)
Uninstall and then reinstall the 32 bit version. The uninstall of the 64 bit version probably removed C:\Windows\system32\java.exe. By reinstalling the 32 bit version that file should be present again.
