To rearm the Office 2010 installation

1. Make sure all Office 2010 applications are closed.

2. Open an elevated command prompt: click start, click All Programs, click Accessories, right-    click Command Prompt and select Run as administrator, and then click yes.

3. Go to \Program Files\Common Files\Microsoft shared\OfficeSoftwareProtectionPlatform.

4. At the command prompt, type ospprearm.exe

   A message similar to the following displays if the operation succeeds: "Microsoft Office     rearm successful."

   Do not open an Office application or run ospp.vbs until you have captured the image. You can rearm 5 times, unless you activate Office 2010 by using a KMS host. If you run out of rearms, Activating by using a KMS host lets you rearm one time.
