Filevault can't be set due to greyed out menu

[micke1967]

Hi I am on an iMac with MacOsSierra 10.12.3
Now I would like to turn on file vault to encrypt my hardrive.
However when going into system tools and following this instruction:
https://support.apple.com/en-gb/HT204837

I get stuck in the menu for selecting iCloud or Recovery Key....
Meaning in this menu the toggle for selecting iCloud or recovery key is greyed out...
So I can't turn Filevault on...

Now Ive had the iMac in 3 years but its still fast and runs well..However I only last week set it so I need password when logging in..
Also I have a Paragon Software installed that makes it possible to read external hardrives on NTFS...
I also have a VM Ware machine going using VM Ware Fusion Software...

So does anyone have any Idea why I can't turn on Filevault?? Why the menu is dimmed/greyed out??
Also are there any better encryption software out there??

Is there a lock icon in the bottom left of the window? If so, click the lock and enter your password to unlock it.

Is it a personal Mac? Do you have profiles installed in System Preferences?

If this does not work, you probably will be able to turn on FileVault via the command line.

Hi yes I did unlock on the lock entering my password before seing that the menu is greyed out.
Its my own iMac at home yes...The only profile is my own...But am at work now so will check when I get home.
If I have a profile what does that mean?? what woudl I then need to do??
And if I need turn on filevault via commandline...what command do i need to run? and do I then get a chance to set recovery key??
And is it safe to do via command line??
It would be very bad to encrypt all files and then not being able to read them like ever...
thanks for your help

A profile can disable some settings.

You can enable FileVault with the following command. It is safe to use, but you need to pay attention. The recovery key will be generated at the end and it won’t be saved anywhere, so you have to keep it somewhere.

sudo fdesetup enable

The command will ask you once for you password (to use sudo) and then ask you for your username and your password again. Afterwards it shows you the recovery key and asks you to reboot. If you have multiple user accounts, then you can enable those afterwards in FileVault settings.
