Feex says

If Arc.exe is open, I would look at Spaces in the sidebar before I call Chrome broken. Dia is a different Browser Company product. chrome.exe is Google Chrome.

What is Arc?

Arc is a Chromium browser with a sidebar, Spaces, and split view. The Windows executable is Arc.exe.

If you have never used it

If you want Arc on Windows, this is The Browser Company Arc, not Chrome and not Dia. Download it from arc.net. Windows shipped after the Mac version, in 2024. Spaces and a vertical sidebar are the tell. Dia is the company's newer browser. chrome.exe is Chrome.

What is it used for?

Sidebar-first browsing

Favorites and tabs live in a vertical sidebar. Chrome uses a top tab strip.

Spaces

Separate work and home sets inside Arc. That layout is Arc, not a Chrome profile switcher clone.

Split view

Two pages in one Arc window. It is still Chromium underneath.

Who is it for?

People who used Arc on another machine and want the Windows build
Users who want sidebar Spaces instead of Chrome tabs
Anyone comparing Arc with Dia or Chrome

Current status

Arc (2024) is a current web browser from The Browser Company. The vendor still points Windows users at https://arc.net/.

How old is it?

Arc launched on Mac first. The Windows build reached a general audience in 2024. The Browser Company later pointed new work at Dia, with Arc kept on Chromium updates. It is not a 1990s browser and not Chrome 2008.

Versions

Major channels first. Exact build numbers are not all verified here.

Common problems

Arc is on maintenance-style Chromium updates

The company has pointed new features at Dia. Security engine updates can continue while Arc feature work slows. Check arc.net for what they ship today.

Windows feature gaps versus old Mac writeups

Arc reached Windows later. A 2023 Mac review can name tools this Windows build never got.

Getting unstuck

Install from arc.net or the Microsoft Store listing

Those are the approved Windows paths the help center names. A random ArcInstaller from a forum is junk.

Confirm Arc.exe, not chrome.exe

The Browser Company folder is this product. Google\Chrome is Chrome. Dia has its own app.

Use resources.arc.net for Spaces help

Chrome settings will not move an Arc Space.

Alternatives

Chrome or Edge for a standard Chromium window. Dia if The Browser Company steered you there. Firefox if you want Gecko.
