Perhaps there's a registry key whose existence indicates a certain JVM is present? If you look at the JRE prerequisite in InstallShield, you might get some hints...

(do MS still do a JVM?)
For the latest Sun JVMs' they are now installed side-by-side. Each verion registers itself in the following key
[HKLM\Software\JavaSoft\Java Runtime Environment]
There is a key for each version of the JVM installed, so you could determine whether the version you require is already installed using this (and installed your required version as necessary)
