Microsoft Office Professional 2010
 

I downloaded Microsoft Office 2010 Professional Plus Keythe Microsoft Office Home and Student 2010 60-day trial and it has expired. I wanted to know If there is any way I could just buy a Product key instead of having to buy the disc?You can get the product key at Amazon for $109. But it's important to remember that then your version is only good on that PC. If you buy a new pc next year you won't be able to transfer it over. If you pay a little more and buy the disk, you will still have the program on your next pc as long as it's removed from your old one.So just now, my pc wouldn't boot, and none of the repairing stuff would work Office 2010 Upgrade Key(system restore, using the win7 disc and doing startup repair) none of it was able to make my machiene boot. so inevitably i reinstalled windows including formatting the drive.here is my problem, when reformatting i lost all my programs, including office 2010 that costs a big chunk of money. so its gone, and i don't have a disk, just Office 2010 Home And Business got the installer online and bought a product key from microsoft. how can i get my key back? i really don't want to have that money go down the toilet. how would i be able to get it back or get another one? If you bought it from the Microsoft website when as a Digital Download when you purchased it Microsoft sent you an email message Microsoft Office 2010 Professional Product Key detailing your purchase of OFFICE 2010. So, just search your Emails for Microsoft and once you find it will contain your Product Key. Search the email you used when you purchased the Office software.I Downloaded Office 2010, install and already have a product key. But When I Activate In Word 2010 It's say"A communication error has Microsoft Office Home And Businessoccurred. Please Verify that you have connectivity to the Internet and try again(0x80072F8F).I see my network I purchased product key card for office 2010 home and student version, but unable to download the Microsoft Office 2010 Standard Key installation file. I tried using cc-cleaner also but still, unable to download from microsoft office site.
