Anyway, I don't understand why Acer offers version 2.x if we are unable to install it. It says it's for Windows 8 (no upgrade only). I have Windows 8 without upgrade and I still can't install it.
I HAVE THE SAME PROBLEM MY WINDOWS IS 8.1 X64 OEI AND PC IS ACER M3-581T WHEN I WOULD LIKE TO FLASH THE BIOS FROM 1.13 TO 2.17 FOR I ENABLE THE UEFI AND BOOT SECURE I GET AN ERROR MESSAGE YOU MUST TO FLASH YOUR BIOS TO SAME TYPE 1
Acer Aspire M3-581TG
Original bios link:

Download the BIOS_Acer_1.13_A_A.zip file and unpack by winrar then get a folder with Others two folder (Dos - Windows) then unpack by winrar in "Windows" forlder the MA50V113.exe file and You get the InsydeFlash folder original with bios 1.13 original, so rename the MA50V113.ROM as MA50V113.ROM.ORG and copy into the patched one and rename it as original MA50V113.ROM , then use InsydeFlash.exe to flash bios !, anyway I think that if You got the new 2.17 UEFI update You don't be able to downgrade, may be a possibility.
Download the service manual e look in, it's a UEFI bios from the origin :

Want to update from 1.13 to 2.17. But I can't find any sting like DisableSecureCapsuleFlash=1 via HxD in MA50V217.exe though it is present in platform.ini.

try open bios isflash.bin with winhex then check

I think all of the above changes are required when we flash a modded bios.
Anyway, thanks.
A You see it'spossible go forward, but I don't know if it's easy to came back, but may be possibility !
