Where old release of Windows_10_IoT_Core_for_RPi.msi creates .ffu image?

Question

I try to flash old version of Windows IoT 10 Core to Raspberry Pi 3.
I downloaded from here the .iso with .msi installer in.
As mentioned here the .ffu need appears in C:\Program Files (x86)\Microsoft IoT\FFU\RaspberryPi2, however there is a new .ffu file, of Latest Windows 10 IoT Core builds.
I searched with Total Commander and found one more file in this place: C:\Users\olga\AppData\Local\Temp\RPi2\msi\msicontent\Microsoft IoT\FFU\RaspberryPi2

Is there some convintional place for .ffu, or what the conventional way of downgrade the Windows IoT Core image?

Answer 1

Yes the default path that FFU install is C:\Program Files (x86)\Microsoft IoT\FFU.

If you want to install an old version please check if there is already a version installed on your machine at first. You can check the default path to see if there is a flash.ffu in RaspberryPi2 folder, if it is uninstall it via control panel:

Then install the old version. You will see the flash.ffu under C:\Program Files (x86)\Microsoft IoT\FFU\RaspberryPi2 if install successfully.

I searched with Total Commander and found one more file in this place: C:\Users\olga\AppData\Local\Temp\RPi2\msi\msicontent\Microsoft IoT\FFU\RaspberryPi2

For this issue, please check the path in the setup operation:
