Do not understand why ?! Both SLIC - 2.1, MSI motherboard -> MSI SLIC just install MSI Certificate & proper Win7 OEM:SLP key
Well, I had to replace motherboard on my PC which was Asus and Windows was linked with this motherboard. The key I have, is not working with MSI Slic.
Thank you. I will report back if this went successfully or not. By the way. Is there any tutorial on how to add slic to BIOS (UEFI) on new (newest) motherboards?
