Still working to get KiCAD loaded for Win7
Do you have any problem with downloading KiCad V5.1.12 (last V5 release)?
Since V6 KiCad needs Win10.
At my Win7 PCs (one at work and one at home) I still have KiCad V5 installed, even I don't use them.
Probably comes with that "get what you pay for" deal, but even within each rev, there are like 15 flavors, and no documentation. In short, I've loaded probably 5 variants.
There are 4 files with KiCad 5.1.12 versions for Windows.
kicad-5.1.12_1-x86_64.exe - is the file I have used to install KiCad at my Win7 64bit system.
"-lite" means it is only program without libraries (libraries changes only when major version number changes so if you have them installed with 5.0.0 you can save on downloading by downloading next V5 releases without libraries.
"-i686" - it can be for Win7 32 bit system, but I'm not sure of it.
