Unable to install BIOS upgrade on Swift 313

Maham Member Posts: 5


I downloaded the latest firmware "BIOS_Acer_1.10_Windows" from Acer website, executed and it alerted FlsHook.exe failed signature check.

How can I install the upgrade?

    You should likely be installing 1.11 now instead of the 1.10 that was out back in September 2019...

    Try running the install application using "Run as Administrator".
