Strange, I never had this problem. Though I am usually extracting the
.exe installer and then put the .msi file on the software share. Usually
I leave one or two previous versions there in case I still need them -
probably that's why I never had problems with it.

In any case it is recommended anyway to remove old Java versions instead
of leaving them on the system. The reason is that the MSI packages from
Sun do not remove the old version - so it remains installed.
Unfortunately it is quite useless to install the latest bugfixed release
if an application exploiting security holes within the Java VM could
simply run the old VM which is left on the system. It's like installing
a second (more secure) door to a house leaving the old one with holes in
place...
