Hi,
> I read it but I got confused... What's happen if you REMOVE a service?
If you had really read this procedure completely, you would have understood that deleting wampapache or wampmysqld service does not have any consequences since you would have seen that the services can be reinstalled without any problem.
On the other hand, regarding databases, the only method to transfer a database is the export/import to SQL file, which you must have read in the procedure as well.
Nevertheless, you have uninstalled your version of Wampserver without doing any preconditions.
Retrieving a database from the data folder is almost doomed to failure.
However, before continuing along this path, it is essential, above all else, that Wampserver 3.1.7 is fully functional, so please
