IFL 4.04 keeps asking for user name and product key every time I boot from its usb stick.
That never happened with other versions, such as 4.1, 4.2, 4.3.
I used Windows 11 to run makedisk.exe, using the middle of the three options on the first window and taking the defaults after that.
Sometimes I have used Hiren's boot cd.
So ... what am I doing wrong?

Probably was entered wrong when creating the UFD. Create another one and ensure the name/key for V4 are correct.

Thanks for your help.
I probably had used the key from version 2 or 3.
It's working perfectly now.
Much appreciated.
