I have downloaded Microsoft Office Visio nad now its not working whenever I open it, asks for YOUR PRODUCT KEY

You will need to contact Microsoft or an authorized reseller in order to get a genuine product key. Getting an activation key through these outlet will also prevent activation issues in the future.

no problema just contact support @ microsoft with your purchase information and they will re send that information we do not provide license keys at fixya.com
