Install User manager

HI
Im using mikrotik RB750 Gr3 and a cant install user manager package.Can somebody help me?
Thank you.

This device runs on MMIPS architecture which does not support User Manager at the moment:
https://wiki.mikrotik.com/wiki/User_Manager/Introduction#What_is_User_Manager
“The MikroTik User Manager works on x86, MIPS, PowerPC and TILE processor based routers and CHR devices”

Thank you.Its posible to downgrade to earlier versoins?

What do you want to downgrade?
User Manager does not work on MMIPS.

Thank you BartoszP.
Can I configure the usermanager on one RB to manage 3 or more hotspots?My idea is to manage 3 or more hotspots users from one interface(one usermanager where I can add multiple hotspots)

Yes, you can. Database will be the same for each server and each server will use same database for authentication. You can not create multiple groups of users and then select on which Hotspot it can connect and on which he could not.

Tank you again.Another question if I can.How to edit the login.html file to not ask for username,only for password.I read a few tips about it but does not working.thank again.

Could you help me please?I want to set the acces with password only,I would like to remove the username field.This is the login.html file:

internet hotspot > login body {color: #737373; font-size: 10px; font-family: verdana;}

textarea,input,select {
background-color: #FDFBFB;
border: 1px solid #BBBBBB;
padding: 2px;
margin: 1px;
font-size: 14px;

}
