Rhino 5 64-bit cant load, loads Rhino 5 instead

Hi, so I recently redownloaded Rhino 5 on my desktop which uses Windows 10 Home version 1803 (OS build 17134.285 & Intel Core 7-7700CPU 3.60GHz, 32GB RAM, 64 processor). So when I launch Rhino 5 64-bit, it took a while to load, but when it did, it gets redirected to the standard Rhino 5 application instead of the 64-bit. There wasn’t any error msg popping up, it just opens the normal Rhino instead of 64 bit.

If anyone could help me that would be great! Thank you

Do you mean that you start Rhino by clicking it’s icon on the desktop or from the start menu, or do you mean you click on a .3dm file somewhere?

I did both, clicking on the shortcut from the desktop and from the start menu.
