Hi there

I installed Xampp on partition D:/xampp (not recommended C) and the first time it worked. A few days later I try to start it and Apache via the control panel and whereas Apache starts, I get an error with Mysql.

This message in cpanel:

Prior to this installation, I had got the same error and made a fresh 64 bit installation on the Win 10 Pro, 8GB RAM notebook.
How can this be prevented?

I do not remember installing this in anyway different from the past, other than specifically or consciously choosing a 64 bit version.

Thank you in advance.
