After installing Office in the Microsoft Store, the icons of Office files are displayed as white icons. You may also see this error when right-clicking the Windows desktop, clicking New and choosing one of the Office apps:

Error 0x8007007A: The data area passed to a system call is too small.


We are investigating this issue.

Note: The issue affects Office 2016 Version 1802 (Build 9029.2167 Microsoft Store) in China and Japan.

In the meantime, you may be able to workaround this problem by resetting the Office apps:

  1. Open the Windows Start menu and click Settings > Apps.

  2. Find Microsoft Office Desktop Apps in the app list, select it and click on Advanced options.

  3. Click Fix, wait for about one minute and then restart your device.

If the problem persists, repeat these steps but click Reset instead of Fix in Step 3.

If Fixing or Resetting doesn't work, you can also uninstall Office in the Microsoft Store, and install Office Click-to-Run (C2R) from your My Account page.
