Rearm Microsoft Office 2010 to Extend License Validity Without Activation
May 2, 2010 | Filed under Microsoft Office;
When you install Microsoft Office 2010, you will have to enter the 25 character product key first before the installation will start. After installation, a Microsoft Office Activation Wizard window will open asking you to activate Office 2010 over the internet or by telephone. If you choose not to activate by clicking on the Cancel button, you can freely use it for an extra 30 days before the product becomes unlicensed. When Office 2010 becomes unlicensed, the program can still be launched but you won’t be able to make any changes and all the icons at the menu bar are grayed out and disabled.
Fortunately you can do an emergency rearm of the activation to give you another 30 days free usage before it turns unlicensed again. All you need to do is to run the file OSPPREARM.EXE file located in C:\Program Files\Common Files\microsoft shared\OfficeSoftwareProtectionPlatform\. This is absolutely legal because the rearm file is created and given by Microsoft for free. Simply run the file and it will tell you that “Microsoft Office rearm successful”. You now have an additional 30 days to use the Office 2010 suite.
You can rearm Office 2010 a maximum of 5 times which should give you 150 days plus the initial 30 days making it a total of 180 days (6 months) of Office 2010 usage without activation.
