Windows 8-10 have driver signing / enforcement turned up by default.
If both kits are official (sounds like they are).
The drivers would normally install during the IDE installation.
If this was not the case you can go to the drivers folder in the Arduino installation and install from there.
I generally recommend doing this as ADMINISTRATOR or with driver enforcement turned OFF. (google)
There are multiple posts about this type of topic so i would recommend you both read the posts at the top of the forum and learn to use the search facility.
A little reading goes a long way.
There are other localised issues that may also prevent driver installation such as Computer ownership, Antivirus, Computer policy's, etc. etc.
