Academic FNC Core no password for login!?

Hello
I registered for TMS FNC UI Pack Academic

I downloaded
Latest registered version (187.39 MB)
and
TMS FNC Core (5.33 MB)
Installation for Latest registered version was ok, I used the password sent by email.

but TMS FNC Core wants a password for installation too
Do I have to buy it?

Sincerely Peter

TMS FNC Core does not need to be installed for TMS FNC UI Pack Academic.
