Error: Failed to prepare registry from offline source

Caused by:

HI
I tried with at least 4 USB sticks, always the same.
I re-downloaded “nrfutil.exe” (again), put it in the USB stick where I unzipped your compressed file and attempted to install it on a physical Win10 machine, even with internet access this is the result:

Then again on this machine I recreated my 'offline' package and tried to install it from a USB stick, this is what I got:

I'll try to update the version on my PC and redo the package, but at this point I have little hope, I'll let you know then, but I'm afraid we're missing something...

Hi, 

Your nrfutil version is quite out of date. Please try running nrfutil self-upgrade and then running it again (for various reasons it is required to do it twice at this particular transtion point but it should be needed to do it twice in fufure.)

If it doesn't recognised self-upgrade as a subcommand then please re-download nrfutil from the Nordic website https://www.nordicsemi.com/Products/Development-tools/nRF-Util

Once you've done either of those then please try the prepare-offline command again.

Hello

I finally understood the mystery, is the twice upgrade ... now have the lastest version and all works, but I'm afraid I can't solve my problem, from what I understand so far I should do the 'nrfutil self-upgrade' command twice which requires internet connection on a machine that doesn't have it... I saw that it depends from the '.nrfuit' folder in the user directory, I have to do some tests then I'll let you know

Hi

I think I have solved my problem, in practice I copy the .nrfutil folder into the Windows user folder (taken from a PC where the tools I need are already installed and functioning) and from the tests I have done this avoids the need to upgrade and installations with active internet connection.

But is there an implementation, C or C++ or other languages, of nrfutil to include in your own executable?

Unfortunately, there are no such resources and currently no plans to provide that.
