PC Innovation, Did you try the link below to download office? Office Download 
Hi, I am extremely disappointed with both Dell and Microsoft.  My client's 3-year old Inspiron 660s had a hard drive failure. After replacing the hard drive I proceeded to perform a factory recovery. The recovery process did not work!!! My concern was that my client paid good money to buy Microsoft Office when he ordered from Dell in 2013. I spoke with Dell support and they confirmed that factory installed software is not included in the recovery partition. Dell do not provide software disks. I then spoke with Microsoft and they said they do not provide downloads for OEM, only retail versions. By the way they understand my client's dilemma and are very sorry.  Now that is ***!!! So here we have a classic situation where neither multi-billion dollar company will help a customer. I wonder what other Dell clients do when they loose software due to hard drive failure? Thanks for listening to my rant.
