Hi Stefan,
it is most important to put the hexadecimal values (bytes) in ascending order into a string array (don't forget: the very first index is 0)! This is a bit annoying if your binary values to set are of a rather long size. The registry entry has to exist prior to writing the bytes into the registry.
As an example with writing 3 bytes, try this:
