This function writes in the program files\ISA2 directory. Vista or Win7 obstructs writing in this directory and instead puts it in the VirtualStore directory. This directory you can find at: [change "Andre" with your own log in name]
or (for 64bit windows)
C:\Users\Andre\AppData\Local\VirtualStore\Program Files (x86)\ISA2
This problem will be fixed in ISA3
