World/Swords of Xeen - Batch file issue

[St_Eddie]

Hi,
I'm attempting to get both World of Xeen and Swords of Xeen running via batch files (as I am compiling a LaunchBox games collection which incorporates ScummVM). I have been using this method for all of my ScummVM games with no issues. However, for some reason, the method is not working for the two Xeen games.

Note that both games launch perfectly well when going through the ScummVM UI itself, so game files are not an issue. I'm wondering whether there is some kind of specific command line which needs to be used within the batch file? My current batch files for the two games read as follows...

------------------------------------------------------------

scummvm.exe -c .\scummvm.ini -f worldofxeen-cd

------------------------------------------------------------

AND...

------------------------------------------------------------

scummvm.exe -c .\scummvm.ini -f swordsofxeen

------------------------------------------------------------

I get the following message when trying to run the batch files(s)...

------------------------------------------------------------

Thank you.
