Hi,
> Ok I stopped/removed all wamp services from my old 3.06 version
An update program allows you to update without changing the user parameters.
So, Wampserver3 update 3.1.1 updates your Wampserver 3.0.6 without you having to do anything other than run - as an administrator - that update program.
It doesn't change anything about the Apache, MySQL or PHP versions you use.
If you want to change Apache, MySQL, PHP or add MariaDB later on, simply use the "addons":
See :
WAMPserver 3 - All you need to knowThere, you embarked on a complex procedure that was not applicable.
Return to your original version 3.0.6, then upgrade to version 3.1.1 and, if necessary, add the Apache, MySQL or PHP versions you want.
It is noted that, with regard to update 3.1.1:
UPDATES
-- Wampserver 3.1.1 32/64 bit x86_x64 (Cumulative Update.)
You are strongly encouraged to apply this update. This is a cumulative update. There is no need to apply the old updates 3.0.1 to 3.1.0 before applying 3.1.1. This update will be required to install the latest Apache, PHP, MySQL or MariaDB addons.
