Re: Chipset x64
For driver signing, only the OEM can fix that. The current Intel chipset drivers are v126.96.36.1999 from here:
I will use these to update the Chipset DriverPacks but the driver date/version have not changed for those unsigned drivers.
The /forceunsigned flag is generally not recommended but will not cause problems unless the driver files have been tampered with, then you will have a compromised install source. If you are 100% certain of the unsigned driver source, then use the flag.
The only other way to "fix" the error is to delete the unsigned .inf from the packs.
