To save time trying to download a 1+ gigabyte installer file so I can put KiCAD 7.x on my Windows workstation (because of how the network comes into my building at work), I downloaded the installer at home on my Mac and brought it in on a thumb drive.
I did this with KiCAD 6.x with no problems (initial install and a later upgrade). When I tried this with the latest Windows version, the installer complains of an integrity check failure and quits. Did something change with the installer packaging or are there just too many moving parts in my method?
