Hi Robot
We're sorry for the inconvenience, we lack MySQL and PostgreSQL drivers in the Windows installer 3.2:
https://community.kde.org/Kexi/Releases ... own_issues
They are known to work however and shall be added at later time, MySQL earlier, then PostgreSQL.

In the meantime, at least for test purposes, KEXI 3.1.0 can be installed because it contains the MySQL plugin: https://community.kde.org/Kexi/Releases#3.1.0
Good thing that we always want to assure is that multiple versions of KEXI can be installed and used on Windows (just the .KEXI file types are associated with last version of KEXI installed).
