Audirvana 3.5 installation and update

I was trying to update my Audirvana 3.5 because I had a previous version, but everytime I clicked on the update button Windows displays a window that says “The administrator blocked the installation and I need permission” (that’s not the accurate translation, I apologize about my english since it’s not my mother tongue) So I tried to uninstall Audirvana and download it again but the audirvana link opens windows app installer and it displays the same message, My account has administrator rights and it’s the only account on this desktop. Does anyone have a solution for this?

Thank you in advance.
