How to Reinstall Microsoft Office If You Lose It?

Reader Question:
“Hi Wally, Please help!! I can’t use office on my computer anymore. It shows an error and quits. I’ve tried restarting the computer but its still not working right. How do I fix this?” – Nancy H., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: Microsoft Office is integral to the function of many businesses. It helps us type documents, make presentations, and maintain accounting records. It can be a huge problem if there is some sort of major failure and you can no longer get office back up and running again. Here we will try to explain how you can get office back on your computer.

Install Microsoft Office

Install the same version of Microsoft Office that you had on the computer before. You should have the disk of Office with you to do this. You can also get it online.

I’ve Lost My Microsoft Office License Key

When you are done installing Office from a disk or from a website online, you then need to enter a valid product key to start using it. You can contact Microsoft if you bought your copy from them. You can give them your details such as the email address you used to buy the copy of Office with, and they should be able to give you your product key.

You Want To Know The Product Key While Office is Still Installed But not Working

If your copy of Microsoft Office isn’t working and you’re trying to reinstall office on the computer, then you can use a third-party key finder software to find the key that is stored in Windows. You can then enter this product key when you reinstall the same version of Office on your computer.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
