DXO 3 windows 10 instalation problem

HI guys, I have this message pop on the screen when trying to install a tryal version of DXO 3 but I have DXO2 (full, paid version) already on my computer. So, i uninstall the old version and now neither one can be installed. The same message will pop on the screen.
Thanks, I hope someone can help !

Good morning,

@alex, could you, please, have a look?

Thank you,
Svetlana G.

Hi @alexandru_p,

Could you please try to install DxO PhotoLab 3 in the Windows Clean Boot mode? Here is an instruction on how to do it.

Best regards,
