My command line is (with or without the -ExportFile command):
D:\Installations\LDRAW\LDView64\LDView64.exe D:\LEGO\Python\data\3001.ldr -DefaultLatLong=20,45 -SaveWidth=500-SaveHeight=500
If that's really your command line, the lack of a space between -SaveWidth=500 and -SaveHeight=500 will likely cause it not to work.
