I have just bought The Office 2007 package for my laptop. I am using Windows Vista. When I load the cd to install it,it prompts me to enter the products key, which it excepts. Then I clicked Upgrade it began installing. Just as it reaches the end it stops and an error message come up saying 'Windows installer has encountered a problem and cannot continue'. It then searches for a solution but nothing comes up and it promts me to cancel in installation. Am i doing something wrong or is there something I need to change? All help needed. Thanks:upset:
