thanky you, juan, for your help, but i still cannot create my disks properly.
i already searched the whole ni faq.
the problem is, i cannot create a distribution kit from my computer, but a co-worker of mine can from his computer, although all the files are in the same directoy.
i copied the project files, consisting off my c and header files, the icon and the project file itself to a folder which my co worker can access. he did nothing but clicking on "create ditribution kit" - and it worked. i did the same and it did not work.
the folder name: p:\change\!! bla bla\
yes, there are spaces and he could make the disks
the creation starts and aborts after compressing the softspy.exe (the name of my program) with a pop-up:
"Error during build. MediaB
uilder return code 2"
bye,
didi
