Portable "installer" for Windows?
MSI installers require admin rights, which I do not have. https://saherneklawy.wordpress.com/2011/02/12/portable-meld-on-windows/ describes a way to run meld without an install, but it's very cumbersome, requires registering Python system-wide (again requiring admin rights), and is seven years old so I suspect it's heavily bitrotten.
Ideally, something that unzips and can be started using a Windows shortcut. I can help, but I need to be pointed in the right direction.
