You are referring to my guides. Did you follow the instructions in this video? I've added some video comments to explain the ABR mechanism in more detail and address the problem you mentioned. Did you enter the 25 digit product key from the COA during installation? If so just select yes when prompted to overwrite the key as the key of your COA will be there hence the prompt: "Found Key: XXXXX-XXXXX etc.  Warning file already exists   Overwrite?"  This will replace the key on your COA (which would need phone activation to Microsoft) with the Dell SLP key found in the Dell Factory Install/Reinstallation DVD and not require any phone or internet activation.  The key on the COA and the Dell SLP key are for Windows only they do not affect Microsoft Office. Microsoft Office can be activated on an unactivated Windows but theres little point activating Office until Windows is activated. I assume you installed Microsoft Office with your product key and have a problem activating it? Or have you had problems installing it? You may need to activate your copy of Microsoft by phone. You should explain your issues in more detail with Microsoft Office. Where are you getting the Office Key, is it on an MPI card? [IMAGE] [URL]  
Dell Inspiron N7110.  Hard drive crash.   Home made recovery disks did not work.  Downloaded Windows 7 Home Premium from Digital River.  Everything is running fine.  Tried to install Microsoft Office 2010 also downloaded from Microsoft without success.  I am guessing it is because the operating system has not been activated.  I am trying to activate the OS using the ABR program suggested by Philip Yip.  When I run the activation_backup program, I get the following message on the command line screen:  "Found Key: XXXXX-XXXXX etc.  Warning file already exists   Overwrite?"    I really don't know what I am doing here, but the key is not the same product key found on the COA on the bottom of the computer.  Don't know whether I should overwrite or whether that will permanently kick me out of the activation process.  I read there is an alternate procedure which involves calling Microsoft.  Is that true?  any suggestions on how to proceed?  Thanks
