Windows 10 and Calibre?

[rube]

Hi all, I still have Windows 7 but I was comparing notes with a friend today and she says her Windows 10 wouldn't let her install Calibre! I've had a quick browse of the forums but I couldn't see anything listed here. Is anyone else having the same issues with Win10?

@rube - No problems here with calibre on Win10, five machines - upgrades from Win 7 and new machines, 32bit and 64 bit.

Where did your friend get calibre - should be from here http://calibre-ebook.com/

I suspect Windows popped an 'are you sure' message via SmartScreen and/or User Access Control. You should be able to click through them. I think SmartScreen remembers you say something is OK, so installing new versions won't pop the message.

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.

Windows has ADVISED me on software I am about to install.
I have the choice to do anyway (I have seen a few of those latly)

I may have done that. That is NOT a refusal.
Refusal is what you get trying to install 64bit on a 32 bit OS

I would Carefully consider WHAT and WHERE I got the file before doing the install/update anyway

My friend knows about the being asked if she wants to install thing, it wasn't that, but she was tring to install an earlier version (not sure how early) - she has since downloaded the latest and it installed without a problem and she says "woot!" and thank you
