Windows 7 Version Question

[A1_Priest]

The Calibre download page at:
https://calibre-ebook.com/download_windows64

has this statement: ''If you are using Windows 7 or Vista please, use calibre 3.48, which works with all Windows 7/Vista machines, from here. Simply un-install calibre and install 3.48, doing so will not affect your books/settings.''

I am currently using version 4.10.1 [64bit] with Windows 7 Pro 64-bit and having absolutely no problems. But, since I noticed the above statement (it took me a while to see it), I stopped updating Calibre.

BUT, since I have seen no problems, can anyone give me a reason why I should uninstall my current version and install 3.48? Also, since 4.10.1 works with my system, does anyone know why the most recent version (4.15.0) would not also work?

Many thanks for any

The reason has to do with QTWebkit and old video card drivers. In some cases, Calibre 4.x will work and in some cases not. You do have a better chance of keeping Calibre working if you upgrade to Windows 10.

Mostly, (older) Graphics drivers cause viewing issues.

Thanks, but unless Windows 10 gets a WindowsXP Mode, such as is available in Windows 7 Pro, I will be sticking with Win7 (legacy hardware and software issues and Win 10's ''compatibility mode'' is next to worthless for my purposes). But, it does seem that I can continue to upgrade until or unless I have problems, at which point I'll just uninstall the most recent version and reinstall the last working one. Thanks again!
