I ordered mircosoft office pro 2010 on 10th may 2011 and received it 3 days later,I uninstalled my old version (as reading up on reviews b4 buying most people forgot to unistall any version they already had)an installed the version from software for students...I'm so happy with the purchase an I wil be recommending to other students,I Also think its great that it let's you connect with your email address so u can use office anywere by signing into your email account! Big thanks to s4s if you read this Nicola x
