As this is not an official way of installing Arc, if you encounter any issues do NOT report them to the developers, they did not intend for people to be running Arc on Windows 10.
This guide is a bit more manual since I wanted to respect the developers' wishes and not directly link any downloads to the beta of Arc.
I don't know how this will work with updates, you may just need to redo the process to update it, but I'm not sure
- Install this font: https://aka.ms/SegoeFluentIcons (this fixes the icons since Windows 10 doesn't have this font installed by default)
- Download the Arc appinstaller and open it in notepad/some other text editor
- Copy everything inside and paste it into this website: https://codebeautify.org/xmlviewer (this is optional, but it makes reading and copying from the file easier)
- Find the
mainpackage@Uri, it should end inArc.x64.msix, and open that in a new tab. It should download that msix file.
