From time to time, you may need to reinstall Microsoft Office because you purchased a new computer or you're trying to resolve a program error. Or, in Excel 2010 and later, you may need to move between the 32-bit and 64-bit versions. In this article, I'll describe how to download the installation files on demand as well as recover a lost product key for Office.

The instructions that follow are specific to Excel 2007 and later. (I was unable to determine how to download Excel 2003 and earlier from the Microsoft website.) Links are all current as of the date of this article (October 31, 2013), but they are subject to change without notice.

Another reader brought the web site GetSoftwareKey to my attention from which you can buy Office 2010 for $30. I have no affiliation or experience with this site, I simply offer this up as an alternative to paying retail for Office 2013, since Office 2010 isn't being sold by mainstream retailers any more. site http://www.getsoftwarekey.com/...

I need to now how to reinstall Microsoft University without a disc, I have the product key but I no disc. Thank you

My understanding is you'd log into your online Microsoft University account and download the software again from there. It's basically a discounted variation of the Office 365 program.

I have a product key, that was left behind by the tech prior to me. It is a download copy. I have no other information to go with this though. How can I access the account that goes with this product key. To check for number of licenses and such?

You'd have to contact one of Microsoft's customer support channels for assistance with the number of licenses related to a product key.

After having installed it on a old laptop which is no longer functional, I still have both the CD and the associated product key for Microsoft Office Word 2007. Should I expect any problems installing it again on a new laptop? Thx

The only problem I would anticipate is exceeding the permitted number of software activations. If you've only installed it once before you should be fine.

I have the product key but when I download, it appears that the product key is not recognized as a valid microsoft key

Triple-check your entry, as it's difficult to type those product keys correctly. If the site doesn't accept it, then I'm afraid your only recourse is to procure another license for the software. Good luck!

Besides I have purchased Microsoft office. I refreshed my laptop and anytime I click on any word file it ask for a product key. When I enter the product key it show that the key is invalid.

I'm sorry to hear of your situation. Perhaps Microsoft's customer service can assist you, but I have no other alternatives that I can suggest other then purchasing the software again.

I had a hard drive issue with my laptop with has now been replaced & I have Windows 7 back (with most of my files) but I didn't get back Office, so no email, word etc etc.
I only have the Windows 7 key which is on my computer, how can I get back up & running with office without a re-purchase??

no ideas??

None that haven't been discussed already in this comment thread.

I have product key for my pc, can i use same for my mac, because i don't want for pc.

Unfortunately, it's two different products, so you can't use a Office for Windows product key with Office for Mac. The only idea that comes to mind is to set up your Mac with dual boot that puts Windows on it, but you probably wouldn't have moved to a Mac if that were a viable option.

I have my product key, but when I try and download it won't let me finish the process without signing into a Microsoft Account. I don't have one and don't want one, can I do this without creating an account?

Unfortunately creating a Microsoft account is an unavoidable part of the process. You could set up a free email account on Gmail or Yahoo and tie the Microsoft account to that if you have privacy concerns.

Is this a new thing or has it always been this way? I am downloading Office onto new computers at our office, and they are telling me that our company doesn't have a Microsoft Account for me to use, but I don't want to create one that is linked to me personally

I'm afraid I don't have any other background to share other than reporting on the present requirements. You'd have to contact Microsoft directly to see if there's some other way to access the software.

JellyBean and the link to re download Office 2007 worked perfectly for me so I could stop turning my house upside down for my disc. Thank you for the great article!

I've searched for software discs far too many times, so I feel your pain on that! I'm happy to hear I could be of assistance. Thank you for taking a moment to share your experience!

I really appreciate the details in this article. After 2 days of searching for a valid download location for Office 2010 I found yours and it worked perfect! Thank you!

Oh my, that must have been a frustrating 2 days, as there are lots of suspicious locations out there. I'm so glad you ran across my article, and thanks for taking a moment to share your experience!

I'm afraid of getting a virus, after my computer rebooted I lost Microsoft Office and that is the last thing I need. I don't have a product key number? These websites you provided - are they safe?

I can appreciate your concern. Yes, the sites I listed can be trusted, and you'll see in the comments that other readers have had a good experience using one or more of the tools that I've mentioned.

During MS office 2007 installation some error occur after 70% installation and after failed installation.

Please please please please HELP ME.

How to solve???

The first thing I'd try is type %temp% in the address bar of any My Computer or Explorer window and then delete all temporary files from your computer. I'd also run Windows Update and makes sure you have all of the patches for your computer. Beyond that, without physically being at your computer I'm not sure what to tell you. Microsoft does offer free support on Twitter at @officesupport so try that as well. Good luck!

David, Thank you for helping me with obtaining my Microsoft Office product code. I followed your instructions and was able to retrieve the product code from my old computer, and download Microsoft Office onto my new computer! Thank you so much for imparting your knowledge to us people who are not computer literate! I am so happy that I do not have to buy a new Microsoft Office product, when I already paid a high price for the one I had.

Wonderful! Thank you so much for sharing your experience. I know first-hand how frustrating it is to not be able to locate a software installation disc when you need it.

Hi, I was wondering if you knew a way to recover unsaved work on Excel? I spent a long time doing work on it and then I pressed save, it said it had saved but it did not and now all my work is gone. That was my only attempt at saving it and I am short on time, redoing it isn't really an option... Thank you in advance for your help!
