Answer 2

Hi Dave,

I have uninstalled trend micro, after that i have tried inputting my digital key to receive the error 0x803fa067 which i looked up to be an incorrect version of WIndows 10. Strange enough, re downloaded the windows 10 creation tool found here: https://www.microsoft.com/en-au/software-download/windows10 after the whole like 5 hour process that i did that i tried again, with no luck still the same error which wont allow me to activate my version,

Answer 3

Hi lucahaton,

That error is generated by Trend Micro, you must have that installed on your PC . . .

Uninstall that software and restart your PC and see if that error is gone . ..
