After over 1 year since I used this utility on my NUCs (to add SLIC 2.4) I thought I would update to 2.5 and found the utilities did not work (same error as posted before) on some NUCs. No amount of changing date back, BIOS settings, and so on helped.
What I found is that on Server 2016 NUC the utility (X007) worked fine to get status/erase/insert new SLIC. But on Windows 1809/1903 on other NUCs the utility did not work (the SLIC was naturally not used there just added it in the past to see whether it worked).
Booting off Server 2016 (1607) install on these NUCs did work - so something must have changed in "recent" Windows builds with regard to EFI variable manipulation which is why the utility would fail. After erase/insert the new 2.5 SLIC would be seen fine in Windows 1809/1903. Tested NUC7 (i3), NUC6 (i5) and NUC5 (i7) latest BIOSes from this month.
So for anyone that gets errors on NUC regarding EFI - make sure you're using an older Windows build, did not try 8.1 / 7 but I would think it would work.
when i apply to patch (i modifyed the files for 2.5) i get this error : This Tool is not authorized to update this Bios
can someone help ?
See just above what I said - your Windows is too "new". Try server 2016 or similarly older Windows not any '18 or '19 or later.
Server 2019 does not work with utility nor does Windows 1903 or 1809. I have not tried others there's no point.
Just install Server 2016 temporarily, change SLIC. Remove then install Server 2019.
Or use a VM of an older Windows version
