When we try to update Bios to 1.52 from WinPE - then afuwinx64.exe fails with error:
Child process failed. Return code: 55
When we try to update ThinkCentre M720q and M720s to 1.29 in WinPe afuwinx64.exe fails with the same error.
If we update from full OS (Windows 10) the bios update is succesfull
Anyone got some ideas? ... wait for new bios :-)
