Installation and data-connection related issues

Database connection failed, ZError 8888, ZError 8866, or Unavailable database


If you are connecting ove the NETWORK, see the bottom of the page.

Connecting to a DATABASE ON THE LOCAL DISC

This is probably because you have both FireBird and Interbase running,
or the database driver is not running,
or Firebird was installed over a previous running version.
Interbase is the old, and FireBird is the new software that handles
the storing of all the data of Versus.
The solution is to get rid of Interbase and re-install Firebird,
or rarely: uninstall and re-install Firebird.

. TRY THIS FIRST

Look for "Interbase Control Center" or something similar in the Control Panel of Windows.
If it is present, stop Interbase.
Then, under Control Panel again find "Programs and Features",
and, if Interbase is present, click on "Interbase" to uninstall it.
Make sure "Firebird Control Center" is present under "Control Panel",
and make sure Firebird is running.

To find the Control Panel, left-click on "Start" in the bottom left corner
of your PC screen and look for "Control Panel".

. IF THAT DOES NOT WORK..

The default database might be missing. It may solve the problem if you
Manually create the default Versus.gdb copying EmptyVersus??.gdb.

. IF THAT DOES NOT WORK

1) Stop and uninstall Firebird as described above.
2) Uninstall Versus
3) Rename the "Versus" folder under "C:\Users\UserName\" to something like "Versus2014"
. DO NOT DELETE it, you probably want your database again later on.
4) Install Firebird
5) Install Versus
6) Copy the "Versus.gdb" file from "c:\Users\UserName\Versus2014\Data" to "C:\Users\UserName\Versus\Data"
7) Run Versus.

. TWO MORE THINGS TO TRY

1) Reboot after you installed Firebird.
2) Just exit Versus and run it again.

========================================================================
Connecting to a DATABASE OVER A NETWORK

It may be that the FireWall is interfering.
Try disabling the Firewall.

Since disabling a Firewall is usually not the preferred way to do it,
you can also only allow connections to port 3505 of the host PC.
Ask your IT-person to change that setting for you.
