⟩ Tell me what Version Of Mariadb Is Workable On Windows 7 X64?
Any released version.
However, MariaDB 5.2.5 and below were all compiled for 32-bit Windows only. These versions of MariaDB will run under 64-bit Windows, but they will run as 32-bit processes.
MariaDB 5.2.6 and above have 64-bit Windows binaries available. 64-bit binaries (and MSI packages) can also be built from the source, as described in Building MariaDB on Windows.
