Thank you so much @sandips! Managed to progress a little further, I've downloaded what you suggested, created a virtual machine but now I get this error and the virtual machine doesn't load:
Created filesystem with 11/4224 inodes and 1302/16896 blocks
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAXM is not installed on this machine
Sorry to be a pain but any ideas please? I have installed the HAXM accelerator in the SDK manager under 'extras' but I still get the same error unfortunately.
Thanks again
