WampServer

We are having too many problems with MySQL 8.0.x crashing and Oracle can't figure it out. We downloaded the Adddon for MySQL 5.7.43 and have exported our DB from 8.0 but there is no menu item on WAMP server to switch MySQL versions as pr the instructions during the install. When we run the Addon Install again, it says already installed. Am I missing a step?

It's time to take off the blinkers, stop smoking the rug and don't click like a madman!
What's displayed at the end of the MySQL 5.7.43 addon installation?

To change your MySQL Version
Start Wampserver 3
Icon Wampmanager -> MySQL -> Version -> Click on the version number
Wait until the icon again become GREEN
The only one user is "root" without password. It will add users and passwords from the previous version.

Transfer of databases from the previous version must be only performed by export / import in SQL files.
NEVER copy data directories or files between MySQL versions.

As stated in my post, when I clicked on the Icon Wampmanager -> MySQL -> Version -> Click on the version number, ONLY v8.0 was available, not 5.7

So I did have my blinkers off and didn't smoke the rug

Right-Click -> Restart from zero
