Transferring control to Microsoft Office Activation Wizard pop up window

Hi guys,

My laptop died a little while back, and the computer guy reinstalled a version of Office on there over the top of my original one (that I had the product key for). As I don't have the product key for the new Office, every time I open Excel/Access I get the Microsoft Office Activation Wizard pop up asking me to register. Is there anyway I can pass control to that pop up so I can use the SendKeys "{TAB 6}" command to go to the Cancel button and then use the SendKeys "^{ENTER}" to simulate me pressing the Cancel button? Have attached a screenshot to illustrate my question.
