If the issue persists, please follow these steps: 

Step 1
  1. Download Grammarly for Microsoft Office at  https://www.grammarly.com/office-addin/downloading and continue the installation, even if you see that error message.
  2. Then, open Microsoft Word or Outlook as an administrator. To do that, please right-click the MS Word or MS Outlook icon, and select Run as administrator from the dropdown menu.
  3. Go to File > Options > Add-ins. In the Manage section, click Go...
  4. In the COM Add-ins menu, click Add. Paste %LocalAppData%\Grammarly\Grammarly for Microsoft Office Suite to the address bar, and open the folder with the latest version. The title of the folder will look similar to 6.8.261.
  5. In the folder, please look for a folder with a title similar to 5496693E32 and open it. Then, select the GrammarlyShim32.dll file, and click OK.

    Note:     If you see an error message afterward, please try adding the GrammarlyShim64.dll file instead. 

  6. See if Grammarly appears in MS Word or MS Outlook.
