My Acer Aspire S32-1856 works not correctly — it reduces brightness from 90% to 100%, when connecting some devices, some connectors stop working, sometimes the sound disappears.

So I want to update my BIOS. I downloaded the BIOS from the support page, created a "UCP" folder on my hard drive according to the instructions and copied the "R01-A4" file there. But when I run this file as an administrator, a window opens, the words "Reading flash" appear, it reaches 100 percent, then a couple more lines quickly appear (I don't have time to read what's written there) and the program crashes.

There are three BIOS versions on the support page - all behave the same. I even tried to install Windows 10 (I had 11), the program also crashes.

Why does the BIOS flashing program crash? How can I fix it? My BIOS version is "R01-A1L"

    Your Aspire S32-1856 AIO computer ONLY runs on Win-11, so reinstall Win-11 24H2 and update all updates to the last OS build: 26100.3915, afterwards fist.

    After the new Win-11 installation, look in the Windows Update > Advance options > Optional updates > Driver updates > as there should be an Insyde Software - Firmware - x.xxx.xx number, install this firmware, as this is the last compatible bios version R01-A4 for your Aspire S32-1856 AIO computer.

    If there is no Windows Update > Driver updates for the Insyde Software - Firmware - x.xxx.xx number, then open the bios folder > BIOS_Acer_R01-A4_A_A > go to ROM folder > and right click "Run as administrator" > on the bios version: R01-A4.CAP file > as the bios R01-A4 should install like in the PDF AMIUCP BIOS Flash SOP v1.0 guide below, so follow this guide. Good luck and hope this clears this bios update, as you must be doing something wrong and that is why the bios is not installing.
