I need to describe the requirements to install VirtualBox 5.2 on a Windows guest in order to execute a Linux 64bit guest.
Where can I locate the VirtualBox 5.2 documentation?
Should HW virtualization be enabled in BIOS?

Yes. For old docs, check the "older builds" section of the downloads site.

Related FAQ: I have a 64bit host, but can't install 64bit guests.

And just to be clear, there has never existed a version of VirtualBox that could run 64bit guests without VT-x/AMD-v. Regardless of the host.

Many thaks for the answer and for the clarification.
I am still unable to locare version 5.2 documentation: can anybody please post a link?

I also couldn't find a link to the documentation you're looking for, but there is a link to the current documentation, and if you replace the version number in the URL, you get for example: https://download.virtualbox.org/virtual ... Manual.pdf

Well, I meant to simply download the VirtualBox version of interest and extract the UserManual.pdf file - but your method works too!

Many thanks!
