Installing Adobe Premiere Pro: Serial Number? - adobe premiere serial number

I try to install Premiere on my PC, I came across a field where I write the serial number. I have the 17 alphanumeric characters, but not accept?

It has 6 fields with space for 4 numbers in each area. What am I doing wrong? If it is intended only for 17-digit serial number?
