Guide to installing Arc Browser on Windows 10

ArcOn10.md

NOTICE: Arc now supports Windows 10 officially. This guide is no longer necessary.

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

1. Install this font: https://aka.ms/SegoeFluentIcons (this fixes the icons since Windows 10 doesn't have this font installed by default)
2. Download the Arc appinstaller and open it in notepad/some other text editor
3. 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)
4. Find the mainpackage @Uri, it should end in Arc.x64.msix, and open that in a new tab. It should download that msix file.
5. Scrolling down a bit more, there should be two dependencies with their own @Uris, download them both and install them as normal (double click, press install)
6. Open the Arc msix with 7-Zip or WinRAR (others will probably work, but those are the two I've tested)
7. Extract everything inside the folder to where you want the app to be installed

Technically, these next instructions aren't required, however it makes Windows actually recognize it as an app and probably prevents some weird bugs

8. Open Settings, go into Update & Security, then For Developers, and toggle Developer Mode, you'll get a confirmation window, press Yes
9. In the newly extracted files, find AppxManifest.xml and open it in notepad/some other text editor
10. Open the Find and Replace menu (Ctrl + H or Edit->Replace for notepad), for Find what: put 10.0.22000.0, and for Replace with: put 10.0.10000.1000, then press Replace and save the file.
11. Open Powershell (from the start menu usually), then type the following commands.

cd "[PATH TO YOUR ARC FILES HERE]"
Add-AppxPackage -Register ".\AppxManifest.xml"

12. Optionally, disable Developer Mode using the same steps as step 8.

Now you should be able to see Arc in your start menu and have it function as normal
