Cant install 64 bits guests

My PC has an Intel i5-4690 cpu and is running Windows 10 64 bits.
- The CPU supports virtualisation and 64 bits
- VT-x is enabled in the BIOS
- Hyper-v is disabled in Windows
- No other app is using VT-x
But I can only install 32 bits guests.
Can you help ?

Have you actually tried helping yourself? Like, searching the forums for this
exact question? "
Cant install 64 bits guests site:forums.virtualbox.org".
Here's the first link:
I have a 64bit host, but can't install 64bit guests.

Of course, I have read the thread "I have a 64 bithost, but can't install 64bit guests" but, unfortunately, it does not answer my problem since all the issues of the checklist are satisfied and it still does not work.

Well, you should have mentioned that in your original post. How am I supposed to know that you actually tried it? It would have saved us a couple of posts if you had stated the situation from the beginning.
If you say that #1 (CPU supports it), and #2 (enabled in the BIOS), are satisfied then it is #3. Something is grabbing the VT-x and does not let other use it, which is not always obvious:
mpack in a recent post wrote:If (1) and (2) are already taken care of, then make sure that no other host apps are already using VT-x/AMD-v. The usual culprits are system level
debuggers, other
VM platforms, and some resident
anti-virus applications. This has become a particular issue with 64bit Windows desktop and server hosts - especially Win8/Win2k12/Win10, since these may enable Microsoft's Hyper-v VM platform by default: this grabs ownership of VT-x and won't play nice with VirtualBox.
Are you
absolutely sure you have none of the above?
