T620 with Windows 7 Embedded - the system does not have license for the image os
Product: HP t620 Flexible Thin Client
Operating System: Other
I bought a refurbished T620 ThinClient which is running an english Windows 7 Embedded 32bit with 4GB RAM and 16GB ROM.
When I now run the hp Easy Tools installed on the ThinClient to create a USB Windows 10 IoT 64bits Image with English language, everythin works fine: the image is downloaded from the web and put on the stick.
But after booting the stick the setup tells me: "the system does not have license for the image os". What am I doing wrong? The BIOS is already the latest one(L40).
Or is there another way upgrading the operating system into Windows10? There should be an option to download (http://h10032.www1.hp.com/ctg/Manual/c05105005), but that particual window has no further options. And I found no local support can give me a hand on this question.
