Creating a BOOTABLE WinPE ISO File of HBS v. 4.9.1

[Fergie86]

Thanks a lot, Froggie - again! Fantastic what you know about the innards of HBS, quite stunning, really - makes me all the more curious whether you can explain the other problem I encountered when I for a change tried to download the WinPE Components from the Microsoft site, and got the error message: "Failed to run system API (0x166001500000003)"

What could possibly have gone wrong here and where shoud I be looking for an answer/solution? Many thanks in advance!
