I downloaded MSP 2.74 and when I try to run it I get this message:
Could not open map_data/TopoMarsMap.dat
You can find it at: http://mars-sim.sourceforge.net/TopoDat.zip
Download and then unzip in the directory mars-sim/map_data
I checked the folder where I extracted MSP into and the file TopoMarsMap.dat is there. I'm runing Windows XP and have Java 2 Runtime Environment 1.4.0 installed.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I'm not sure why you're getting this error. I don't have access to a WindowsXP machine to test it on, but I talked to a system admin colleage who's worked a bit with WinXP and he couldn't think of anything off hand.
I can think of three possible causes:
Perhaps the file permission for TopoMarsMap.dat doesn't allow the program to read it. You might want to check the file permissions. On Win2000, it's right-click on the file > properties.
The batch file doesn't know the relative path to the file. I would think it would fail from missing other files first if this were the case.
The TopoMarsMap.dat file is corrupted in some manner. You can download another copy of that file and try it again. The URL in the message is incorrect and the correct URL would be:
I got a similar problem when installing it. The windows java-RTE seems to have a problem, when the installation path of MSP has spaces in it. I used another folder(like mars-sim-project-2.74) and then it worked.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I got exactly the same problem under Windows 2000.
I downloaded version 2.73 which ran ok, then found this message.
I downloaded the file from the correct location (the error message gives the wrong file location) which doesn't help.
I then looked again at the actual error message which gives the solution.
C:\download\Mars Simulator Project 2.74\MarsProject_2.74>java -clas
jfreechart.jar;jars\jcommon.jar;jars\aelfred.jar MarsProject
Could not open map_data/TopoMarsMap.dat
You can find it at: http://mars-sim.sourceforge.net/TopoDat.zip
Download and then unzip in the directory mars-sim/map_data
...........
the error message is asking for the file to be unzipped into mars-sim/map_data
so I then unzipped the original download into c:\mars-sim
and it works!
all the best
David.

The classpath command and the new map download fixed my errors.
Thanks to all who submitted help.

Let me know if you are unable to get this resolved. I'd appreciate it if anyone else ran into this same problem would let me know.
Thanks,
