Where is a repair log? You should post it.I got no messages too. But I still can't open it, even after I installed the beta assets.
+set fs_game mbii
+set fs_game mbiibeta
This is normal behavior of the Steam, related to that it switches (renames) jasp.exe and jamp.exe to launch the game.it showed a "Corrupt Zone Header" so I think that may have something with my game being Steam version
To play MBII beta you need to change command line (or shortcut) parameters frommbii.x86.exe worked with the normal MBII, but the MBII beta didn't work.
EDIT: Forgot to mention that when I say that didn't work I tried to say that it still opened the base JKA game, not MBII beta
+set fs_game mbii
+set fs_game mbiibeta
Just for the record: you no need to extract all files from all .pk3, you needed only one file: uix86.dll from MBII.pk3.For some reason WinRar didn't extracted all the files from MBIIBeta folder
The second option, it extracted like 5 archives from .zip and MBII.pk3 wasn't one of themJust for the record: you no need to extract all files from all .pk3, you needed only one file: uix86.dll from MBII.pk3.
And in fact, even that file should be unpacked by the game; if it failed to do so, that means there is a problem with access right of GameData\MBIIBeta folder. To see those rights, right click on MBIIBeta directory => Properties => Security tab, write access must be allowed for your account.
Edit: or did you mean WinRAR failed to extract contest of Beta distributional .zip? ... If you did, then yes, that was a reason why beta failed to launch.
