I get the same error as JW90

@VH2000 -- did you use an HP computer or a non-HP computer to run that ".exe" file?

It works correctly for me, on a home-built desktop PC and on a Lenovo desktop PC, both running Windows 10.

@Itsmyname I appreciate the attempt to help but is it really that hard to upload the files on some sort of file sharing website? Unless they are unique to the machine they were extracted on, which is not really the case?

[itsmyname]

@JW90 -- it launched on the other PC, and let me create the USB drive, the structure was 3 folders,  with "Hewlett-Packard" and "EFI" included.

Is there a ".bin" file in any of those folders, with a size of 16,777,216 bytes?

[JW90]

Yes but it's not the same size, because that's the oldest installer, F.31 doesn't run for me and that's why I asked you to upload the files.

[itsmyname]

@JW90 --  it's not the same size

What size, and date/time, is it?

[JW90]

Nevermind, cross that. It is 16MB (16,777,216 bytes) and the creation/modification date seems to be today not in the past, but it comes from 08526F02.exe and not 08526F31.EXE as it doesn't launch.

@JW90 -- put that file into the "root" directory of the USB memory-stick. If there is a ".sig" file, also copy it.

Then, the BIOS Recovery program on your HP computer should be able to find the file(s), and apply the update.
