I've been running various versions of calibre on Win10 since last August. I also run it on Win8.1 and, in the past Win8.0 and WinXP. I've never had an issue with Win refusing to allow calibre to be installed.
I have had one instance of Windows Defender on my Win8.1 device (8" Dell Venue 8 Pro) incorrectly reporting that the 32bit version of calibre v2.53 was malware and it promptly deleted the calibre.exe. It didn't do this initially and initially calibre ran fine. After a week or so Defender stepped in and after displaying a warning dialog it deleted calibre.exe. It did the same thing when I reinstalled 2.53 so I simply installed an older version v2.51, which Defender accepted as clean. I've since installed v2.54 successfully. I admit that I was too lazy to retest 2.53 after the various definitions updates to Defender to see if any new virus definition corrected the error, thought they must have been the root cause since v2.53 ran fine initially. The same 32bit v2.53 never disturbed Windows 10 on my desktop with its version of Windows Defender active.
There have been occasional reports of various anti-malware software incorrectly flagging calibre as being suspicious. Perhaps the person having difficulty with "Windows 10" refusing the install is really having an issue with their anti-malware software. A new set of updated definitions and/or a different version of calibre might resolve the issue.
