Upgrade Wampserver 3.0 to Wampserver 3.1.9 - 64 bit (no replies)

Hi i want to update wampserver 3.0 to 3.1.9

My installation is 64bit on windows 10, in the folder C:\wamp64

I have checked and installed the necessary Visual C ++ packages

I downloaded Wampserver update 3.1.9 cumulative update

During installation, i choose the same folder of wampserver 3.0 "C:\wamp64" or default folder C:\wamp?

After this update, what needs to be installed?

thank you
