Hi, at work we've purchased couple of used PC's with Windows 7 Pro installed on them. We then purchased Office 2013 Home and Student OEM versions. Problem is that they've got only 1 year warranty and if something happens I won't be able to transfer them to another PC. I don't know if I buy from somewhere the same PC with another Win7 Pro installed will I be able to use Office 2013 for which I already paid 250 Euro? If you're familiar with virtualizing solutions adn what options do they provide for licensing applications?
