1| Is it possible to pass on your full system's specs inclusive of your OS and your audio equipment?

AMD SYSTEM USERS
If you're using an AMD system you should connect your Scarlett Solo to a USB 3.0 port after downloading and installing the driver.
If you don't have any USB 3.0 ports available on your AMD system, please download and install this driver instead before connecting your Scarlett Solo to a USB 2.0 port.

Right click installer>Properties>Compatibility Tab>Windows 7/8 [from drop down menu]
or with an elevated command:
Right click installer>Run as Administrator
