Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Your Microsoft 365 subscription does not need to be transferred manually; install Word on the new computer and activate it by signing in with the account associated with the subscription.
Install and activate Word now
- On the new computer, open https://m365.cloud.microsoft/apps.
- Select Sign in and use the same Microsoft account—or work or school account—associated with the Microsoft 365 subscription.
- Select Apps in the navigation pane, then Install apps in the upper-right corner.
- Select Microsoft 365 apps.
- Open the downloaded installer and approve the Windows prompt by selecting Yes.
- Wait for “You’re all set! Office is installed now,” then select Close.
- Open Start, type Word, and open it.
- Sign in with the subscription account if prompted and accept the license agreement. Word should then activate. ^1^
No new product key should be needed when the subscription is already associated with that account; Microsoft 365 activation normally occurs by signing in. ^2^
Request a live Microsoft support agent
Use Microsoft’s official support page: ^3^
- Under Microsoft technical support, select Get help.
- Enter: Install and activate my existing Microsoft 365 subscription on a new Windows computer.
- Continue through the prompts.
- If automated help does not resolve it, select Contact Support.
- Choose Microsoft 365 and Office, then the activation or installation category.
- Select the available chat or callback option. Availability can depend on product, account type, region, and support hours.
Do not post your telephone number, email address, password, or product key in this public Q&A thread. Enter a callback number only within Microsoft’s official support form.
If the subscription is not shown
If the installation page has no Install apps option, the likely next check is whether the correct account was used. Microsoft provides separate account-recovery guidance for forgotten usernames, passwords, multiple accounts, and accounts that are not working. Support agents cannot reset passwords or directly change protected account details. [^4^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft 365 for home")
If Word opens but displays the Activation Wizard, complete its prompts. If activation still fails, use the official support path above and provide the exact error message shown—without sharing account credentials or product keys.
