I was trying the same thing... here are the steps that worked for me.
Click on restore backup
Navigate to the folder where your quickbooks data is stored on your computer (like desktop, or documents)
Find the company file you want it ends with .QBW
at the left is the column that says version - click on choose
click on continue
a window will appear with the dates of your backups for that company file,
click on the date you want to restore
Click on Close
click on continue
You can now decide to copy the files to a new location (I recommend)
Type in the name for that new location
click on OK
Wait until the restoration is done
Go into Quickbooks and open the restored file from the new location
Sorry the numbers feature in this response doesn't work so I couldn't number the steps. Hope this will help someone else.
