The fix for this bug is applied in a form of registry edit at the end of installation process. Apparently something on your PC prevented registry change.

Re-install the game as administrator, preferably somewhere outside Program Files folder. That should be enough.

Remove any compatibility settings.
Go to installed game folder and double click 'WarlordsBattlecry.cmd' file.
If you have file extensions hidden, it should be the one described as 'Windows Command Script'.

I sent you a PM with the same replay, but in case someone else run into similar issue I'm reposting it here.

The error you got is not exactly what I would expected, I've no idea why cmd would look for .sdb file in Windows folder when you're running it locally from game directory. But anyway, if we specify both paths directly, it should work.

Please open that WarlordsBattlecry.cmd file in notepad and change the first line to something like this (quotes are mandatory):

"c:\windows\syswow64\sdbinst" "[YOUR GAME FULL PATH]\warlordsbattlecry.sdb"

^ that's for 64bit systems, if you have 32bit Windows, replace syswow64 with system32.

For example, for me it would look like:
"c:\windows\syswow64\sdbinst" "W:\GOG.com\Warlords Battlecry\warlordsbattlecry.sdb"

I've removed '-q' switch, that way you should be notified if the fix was applied correctly or not. In this case, '-q' stands for silent install.

Please let me know if that works, normally you shouldn't have to go through all this just to play the game. However, you are the first person to report such problem.

In that case, could you use this link and contact our Support?
