How to upload sketch to Arduino UNO in Windows 8.1?

Question

Arduino

Good people, tell me please.
Did you get a payment from aliexpress? Connected to the computer. 2 lights are on, "ON" and "L".
Trying to load native Blink example, gives following error.
Arduino: 1.6.6 (Windows 8.1), Board: "Arduino/Genuino Uno"
The sketch uses 1,030 bytes (3%) of the device's memory. A total of 32,256 bytes are available.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum: 2048 bytes.
avrdude: ser_open(): can't open device "\\.\COM1": The specified file could not be found.

Google didn't help much. When I connect an arduino board to my computer, in the device manager, in the "other devices" drop-down menu, "USB2.0-Serial" appears with uninstalled firewood. I'm trying to install firewood from the drivers folder, which is in the folder along with the Arduino IDE, it says that I did not find drivers there.
Who faced, help.
