MSFS appears on two drives

Hi, I hope I’m not confused and did something wrong now too.

In preparation for today’s beta I uninstalled MSFS and reinstalled it in a new folder c:/Georges FS.

When I install the beta later I was going to install it also on my c: drive but in the long default location c:/users/George….

I think I will now have the ability to run either SU7 or the new beta. Do I have that right? If so, how do I know how to start (select between) the two different installations?

Thanks for your time and information!
