the problem is: on the same PC, I've to use JRE 1.3 for a web application and JRE 1.4 for another.
To use the first application I've to remove JRE 1.4, install 1.3 and reboot.
For the second, the opposite: remove JRE 1.3, install 1.4 and reboot.
I don't want to reboot the machine, I'm trying to write a script or a batch file to change the release quickly.
I tried to copy in \windows\system32 the java.exe release that i need and also change the "CurrentVersion" value in the register but is not working.
For example to configure one browser with JRE 1.3 and another with JRE 1.4 is not working.
