I also got "Agilent LXI error" error when installing 5.71. Perhaps this is normal, because this installation package is for different oscilloscopes and for ours it is simply not needed. I'll try to clarify/confirm this somewhere.
You have no activated options, in the options section "none"
I did the installation of updates in this way:
1. Install package 5.71, go through problem with Agilent LXI.
2. I reboot the scope and start the installation again. This time the installation will complete.
3. I replace the agscope.exe file with a patched file.
4. Copy license.dat to the same directory as agscope.exe.
Partitions are smaller because you restored partitions without changing their offsets. If the offsets are changed and the partition is extended, then the Smart Boot Loader will require reconfiguration.
I spent a lot of time looking for a simple and universal solution, but the internal structure with Smart Boot Loader + XP partition + hidden FAT recovery partition cannot be logically restored and each part will need a separate approach. All this is very difficult and useless. So I stopped on two options.
1. Sector-by-sector copying with a free utility for Windows. Fast, accurate and simple. It can be implemented both on the oscilloscope itself without disassembly, and on a normal PC, if the disk is connected via USB or directly. If you want, I can give you a new image. This is much more convenient and a very accurate copy.
2. Restore only the Windows XP partition. In this case, you can implement partition alignment for XP and use all free disk space (expand partition). And for recovery, use the image on CD disks. This is how it was done for the oscilloscope with Windows 98 - there was no recovery partition, just the system and that's it. Recovery is making via CD discs or LS120 in older models.
I sent you the new link, if you want, you can test it. It is more convenient through a regular PC. You will get exactly the same result. You will need to restore the system through the recovery partition. Everything is as before, only easier and faster. If suddenly the recovery partition freezes on the Windows 98 logo, just reboot, don't wait.
