I´m getting the following error:

When I try to run TB OSD Tool Script 4.45 from IFW 4.02 installed and select

Physical Drive > select Windows installation to process > HD0 Windows10_OS... (C:)

It fails with the message: Unable to access Windows installation.

What could be happening? Any suggested solution?

Looks like that's the running Windows system. If so, you would need to run the script from outside of Windows (TBWinRE, IFL, BootIt, etc.) to access it.

Yes, that was the problem. Thanks.
