Problem with installing the Wireless LAN Atheros driver on Acer Aspire V5-531 with Windows 7x64

After downloading (to another PC) and extraction on the target laptop the driver "Wireless LAN_Atheros_v10.0.0.274_W7x64_A.zip" from Acer website, error 0x80004005 for data1.cab appears. I tried versions 10.0.0.274 and 10.0.0.225 but the problem is the same. Laptops of this series were sold with Windows 8.1, but a friend gave me this laptop because of a damaged HDD. I replaced the HDD and installed Windows 7 x64 Home Edition OEM version - all drivers were installed except for the wireless card (also Bluetooth, but I don't need it). The problem is that this model does not have an RJ45 interface, i.e. a wired network adapter, so I cannot connect to the Internet other than via wifi to download the necessary updates using Windows Updates. Help on various forums ended with links with "Error 404" pages or: Open "Settings" then "Network Adapters" and run ... . It looks like Joseph Heller's "Catch 22"...I will be grateful for your help...

    Use this site "Unofficial Qualcomm Atheros drivers website" and look at your OEM Qualcomm Wi-Fi/BT cards model number and get their drivers as they have all the drivers for your V5-531 Wi-Fi and Bluetooth for OS's of XP, Win-7, 8, 8.1, 10 as that driver that you are showing is probably not compatible or you need to completely delete the old drivers and reinstall the right drivers or your card or and if its damaged as its old then buy a new one (its only cheap) see caption below.

    Also I strongly suggest that you run Win-10 not Win-7 or Win-8 as this laptop has a GUID (GPT UEFI BIOS and will run Win-10 easy as you will have less driver problems and I hope that you have upgraded to a 2.5" SATA SSD drive and put the max RAM and are running the last BIOS update to run Win-10? Btw I speak from experience as I upgraded an Aspire V3-571G which is a 10 year old laptop on Win-10 since Win-10 was released but I upgraded it to a 2.5" SSD, BIOS update and its max RAM on this laptop and it worked smoothly and 100% on Win-10.

    These are the OEM Acer fitted Wi=Fi/BT cards fitted to the V5-531, the last one is the Qualcomm fitted to your laptop:

    Thank you for your answer. but after visiting https://www.ath-drivers.eu/ and downloading the package, I didn't find "Setup.exe" or something similar. What should I do ? I can't install Win 10 or any other Micro$oft system - I don't have a source. I can only win 7 because I have a cd with a license key for Win 7

    Update
    After extracting the directory "Wireless LAN_Atheros_v10.0.0.274_W7x64_A.zip" downloaded from the Acer website and "win7-10.0.0.336-whql" from the site you provided, replace the files in the "ndis6xWin7" directory in "Wifi_DriverOnly" from the "Wireless ....." directory with the files from "win7-10.0.0.336-whql". Now the wifi card works.
    Thank you very much
