# Installing SecureMailMerge

> You install the SecureMailMerge plugin via the Apps menu regardless of which operating system (Windows, Mac or Web) you are working on.

## Step 1. Open the Office Add-In Store from the Apps Menu

Locate the "Apps" or "All Apps" icon on your ribbon menu and click it to open the installed apps. Head to the bottom and click "Add Apps" to open the AppSource Office Add-In Store.

**Note:** If you do not have an Apps menu but rather a "Get Add-Ins" button please see [this page](https://www.securemailmerge.com/help/installing-securemailmerge-addin-for-outlook-using-get-add-ins-menu) instead.
