I can get the game installed and updated, but am having trouble running it (I am using 16.0).
In a clean win64 bottle, I install the following:
.net 3.5 sp1
.net 4.5
visual c++ runtime 2005 & 2008
directx for modern games
core fonts
msxml4
and then Mortal Online
When launching the game, I get the following errors:
err:ole:CoGetClassObject class {6c736db1-bd94-11d0-8a23-00aa00b58e10} not registered
err:ole:CoGetClassObject no class object {6c736db1-bd94-11d0-8a23-00aa00b58e10} could be created for context 0x1
err:winediag:SQLDrivers No ODBC drivers could be found. Check the settings for your libodbc provider.
fixme:d3d:debug_d3dformat Unrecognized 0x34324644 (as fourcc: DF24) WINED3DFORMAT!
fixme:d3d:wined3d_get_format Can't find format unrecognized (0x34324644) in the format lookup table
with several others
The launcher runs well, but launching the game brings up a black screen with the splash logo before closing.
As far as I can tell from the Mortal Online forums, only 64bit windows is supported. It also runs on Unreal Engine 3.
