Hi,
By installing a new version of Wampserver on a PC that already had another one, you installed the new Apache and MySQL services that replaced the "old" services that had the same names.
This means that when you launch the old version of Wampserver, it is the new services that start, so, among other things, the new version of MySQL and not the old one, which means that your old databases are not seen.
- Exit the currently launched versions of Wampserver.
New services must be deleted in order to recreate old ones.
Open a command window as administrator: the word Administrator must be in the title bar.
In this command window, you must type the following commands successively, waiting between each one for the return of the command prompt:
sc delete wampapache64
sc delete wampmysqld64
sc delete wampmariadb64
Exit the command window by exit.
Launch the old version of Wampserver. Of course, the icon will not be green since there are no more services.
We will create the "old" services:
- Left-click Wampmanager icon -> Apache -> Administration service -> Install service.
Do the same for MySQL and MariaDB if available.
It is now time to start the services:
Left-click -> Start services
