commandline rendertroubles

hi all,

i try to get blender to render from the commandline, and later on I wanna do batch script (*.bat text file) for having all files rendered in a specific folder by night.
so when i try to open a file with " blender file1.blend" it works…
but if i try to have it rendered in backgorund “blender -b file1.blend” dos tells me that he can’t determin the argv[0] path…
what does that mean? what i’m doing wrong?

thanks to all!

not sure you should give some examples.
the order of args are important -eg- open a file before renderin it…

i have troubles too

script work OK press ALT+P, but get an ERROR launch it from commandline

i think its an bug, but not find info about this.
