currently it will install a brand new version and you need to uninstall the old one manually. Starting from SDK update 2 I believe the installation is going to become smarter with upgrade possibilities. Just a few more months to wait I guess.
Note that only the JRE will be updated, not the SDK
Thank you so much. Thats exactly what I feared.
Im not going to bother then. Who needs the hassle of installing/uninstalling. Thats 300 MB thats getting deleted and
shuffled about every update.
Do you know if it prompts you to uninstall first?
I didnt think it was advised to uninstall an old version after installing
a new one.
