If you have Office 2010 preinstalled and it isn't the Starter version, your key should be on an MPI card: [URL] However you can obtain it from Belarc Advisor as its currently installed: [URL] Links to download Office are given here: [URL] If it was the Starter version, it is completely obsolete and replaced by WebApps: 
I don't know why but I have 19 Office 2010 updates trying, every day, to get installed and I get error messages. This has been going on for months. At Microsoft Support, they tell me to use the Office product key but the software came preinstalled and I don't have a CD. I'm also having problems with something called "Microsoft Office Single Image 2010" that gets installed and then, immediately rolls back the installation.  People at Microsoft tell me to come to Dell because the software was installed by your company. I don't know what to do and I've spent probably a hundred hours trying to find ways around this problem, to repair the program or fix it. I haven't been able to work on any Office documents since January. Also, I try to use your support system but the diagnostic tests never finish! They can run for hours (and they are supposed to take 2-10 mins) and they just keep whirring away, never letting me move forward in the Support seeking process.  Can you just give me the product key for the Office 2010 software you installed on my Inspiron N5010 running Windows 7? This is my fourth Dell computer but this has been so frustrating, it might be my last. The rest of my family has Macs and they don't seem to have any of these problems.
Office 2010 came preinstalled on Dell Inspiron laptop and now won't update
