Calibre 3.48 and Windows 7
#1  Shykat 02-27-2021, 08:30 PM
I am using Windows 7 on my desktop and I was wondering if Calibre 3.48 is the last version that will work with that version.

Thank you,
Shykat

Officially, 3.48 is the last version guaranteed compatible with Windows 7.

Unofficially: Some people have had success running newer versions, but it's not a given considering the version of Qt used isn't really compatible. And Calibre 5.x installer will fail outright for Win 7 though, so you'd need to extract the MSI.

No, that's 4.23, though if you have issues, go back to 3.48 which is guaranteed to work.

Thank you. I may stay with my current 2.61 as it does what I need it to.

Did you miss the "free update to Windows 10" window? Support for Windows 7 ended mid January 2020, your OS is a big security risk.

Actually, you can still get Windows 10 for free. Here's the URL for a free legitimate Windows 10 upgrade.

Are you sure? That looks like it just downloads the upgrade tool. It probably checks the versions and licenses before continuing. Have you run it recently on a Windows 7 machine?

I did something similar last December when I had to rebuild a machine from bare iron. I built windows installation media as described above, putting it on a USB stick, then ran it. When install asked for the product key I entered the original Win7 key. It happily took that and activated the machine.

Yes, I am sure. It's still free with this loophole. But make sure you have the key for your Windows 7 just in case you need it.

If you had already updated a machine with that key, it is probably registered. But, somewhere else has implied that MS are fairly lenient with this rule. I think it is to their benefit to let as many systems update as possible.
