The file on disk is not the finish line. These steps assume a quiet ten minutes, a working network, and permission to add software on the office laptop.
Windows after ChromeSetup.exe arrives
Open the helper from the Downloads list. If SmartScreen or antivirus asks, confirm you came from this briefing and allow the official file. The helper will continue the Google Chrome download and then start setup. Accept the location it proposes unless IT gave you a written exception. When the first window opens, decline extras you do not need, choose whether to import inbox data, and set a homepage that will not embarrass a projector. Pin Google Chrome to the taskbar if that is how the floor finds tools. Keep the old browser for a few days.
macOS after the package opens
Allow the package to run from the new tab you opened on this page. Drag or confirm as the installer asks, then launch Google Chrome once from Applications. The first window is the same decision set as Windows: import or start clean, sign in or stay local, extra services on or off. A weekday briefing prefers a clean start on a loaner and an import on an assigned laptop. Eject or close the package window when Finder still shows it, so the next review day does not begin with a leftover disk image.
Phones after the store listing
Install from the store button, not from a file a colleague sent. Open Google Chrome once, skip sign-in on a shared tablet, and turn on sign-in only on a personal phone. The mobile first screen is shorter than the desktop wizard, which is why this page told you to decide habits on the office laptop first. If the store page looks unlike Google Chrome, you tapped the wrong listing. Return to this Chrome download page and use the published iOS or Android link again.
Across all four lanes, the last step is a boring check. Visit a known internal page, open the inbox, and confirm the printer dialog still sees the floor queue. If those three acts work, the Google Chrome installation is done enough for a weekday. Fancy theme work can wait until Friday. If something fails, do not download a second helper from a search ad. Re-read the system notes below or open a ticket with the exact file name you used.
