I run Windows 7 Professional Version 64 bit on a Think Center M93p Tower. I do not want to upgrade to Windows 10. I tried both 64 bit and 32 bit and received the same message. I do not have Defender, but I disabled my anti-virus and retried to install without success. I just successfully installed the portable version of Calibre, so that should work for my limited needs.
I don't know why the portable version will install, but not the full version.
Thank you for your help.
Susan

Did you try and disable your Anti-virus (only while downloading from the official site). (I have never had Defender Mess with a downloaded file)
There is an official help FAQ that might have additional tips
