why does my serial not valid
Did you buy it used?
Or what error do you get? You enter it into Native Access and it's a new device?
Anyhow, probably best to contact support https://support.native-instruments.com/hc/en-us/articles/360014498698-How-to-contact-NI-Support
had the old native access and installed the new one.
looks like i can install the new pro 4
thanks
If referring to hardware serial then are you using latest version of Native Access for your OS ? (assuming that you are entering the hardware serial into N.A.)
Else , then as already asked by lord-carlos then what is the exact error ? screenshot of error ? (but please do not show serial on screenshot).
