i dont know how to add some more informations i foud out, so i give them
here in this way as answer.
i found out that the program was made with thinstall version 3.358 and
the vregtool isn't maybe the tool for it, because i tryed it just before with a clean tvr file
and it doesnt work with it too.
but why is it so? is there any information abut the format of a tvr file?
sorry for the late answer and thank you for that link
but it doesn't helps because i use the printstats key and the
error is the same
maybe its the size limit of the tvr file
