[resolved] How to update to 3.9 full function from 3.8

I only install the D+ & firewall component of the 3.8 version before, if I install all component(means include AV,FW,D+…) of 3.9 version, can I achieve that just by use the 3.8 update, or I need to uninstall the 3.8 version, then to install 3.9 V.

You should do a clean install to avoid potential problems. With a clean install you will have the option to install the AV (default) also.

thank you.
