Need to upgrade php in wampserver 3.1.0 64bit (2 replies)

I run moodle on wampserver and just found out that moodle 3.9 requires PHP 7.2.

I am hoping I can update just the PHP using the wampserver3_x64_addon_pohp7.4.7.exe, that I downloaded from [wampserver.aviatechno.net], and not the entire Wampserver.

Question: Will this update know what to do when I run it on my server?

I plan to test the .exe file on a copy of the live server first.


Thoughts?

Thank you.
