My old computer was Windows 7 with a CD/DVD drive and I installed my own legal copy of Microsoft Office 2010 Professional from its CD onto that computer. I recently got a new desktop PC with Windows 10, but it doesn't have a CD/DVD drive. How do I install my legal copy of Office if there is no CD/DVD drive?
I tried this: inserting the Office 2010 CD into a friend's computer and then copying the entire file onto a thumbdrive. I inserted the thumbdrive into my own new computer and copied the entire Office 2010 CD into my downloads file. Then I opened it to install it, and it the install window opened, asking for my 25-character install key. I typed that in, but Windows says it's not valid. I know it's valid.
Bottom line, how do I install legal copy of Office 2010 Pro if my PC doesn't have a CD drive?
