I wanted to update the BIOS a few days ago, so I downloaded the 4ACN38WW64 update from the Lenovo website. The problem is that when I execute the "installer" it closed automatically without any further message.
I checked the batch file (AutoRun64.bat) and I found that there are three different updates (I assume for three different structures/variants of the z370/z470), also a line which closes the program in case it doesn't find any matching device to complete the updating process.
I would really appreciate if someone could help me.

Thank you for your interest, yigit.
I am using Windows 7 x64, but neither the x86 nor the x64 versions of the updater worked.
At first it just closed, and if I looked at the "vgachk.txt" file it was in blank, so I thought that it was lacking some kind of authorization (even when running as admin), so I disabled UAC and ran it again. The command prompt opened and closed suddenly, and now when I checked the .txt file it has the following in it: "No matching devices found."
I thought I could update it manually using the WinPhlash64 application that came in the folder, but I got confused when I saw the three different updates: "4ACN38WA.wph", "4ACN38WE.wph" and "4ACN38WD.wph". I wouldn't know which one to choose.
Edit: Also, the current bios version appears to be 4ACN31WW.
