Upgrading to MacOS from 10.6.8 MacBook Pro

Question

I have 2011 MacBook Pro that I have not used for a while. Now I am back to using it and would like to upgrade to the latest OS available. Currently, it is 10.6.8 an here are the issues

When I try to download the MacOS High Sierra from the App store, the "Get" button is grey and nothing happens when I click it. In fact, all the apps are like this and I cannot use the App store to download anything at all (I have signed it with my Apple ID).
Cmd+R at the booting is not working so I cannot even restore to factory settings.
I do not have recovery disks.

Could you please help me to sort this out as I am not familiar with Mac that much.

You may need to go via Lion to Mavericks to Yosemite to get to where you want to be... Exact steps I have not checked, but that may be why the button is greyed out... — Solar Mike, Jan 23 '18 at 08:08
@abd I did it in System Settings, there's a update icon there. — oblitum, Jan 24 '18 at 14:34

Are you using a 32-bit machine?

Unfortunately, 32-bit systems cannot run any OS after Snow Leopard (10.6). You have a few options:

Keep using Snow Leopard (be extremely careful about security, as I don't think it's still receiving updates)
Buy a newer Mac (possibly used)
Install Ubuntu and use it instead of OS X

If your machine is 64-bit, then I don't know what the problem is.
