getting error

another version of this product is already installed.  installation of this version cannot continue... to configure or remove the existing version of this product, use add/remove programs on the control panel.  

i did my daughters taxes a week ago, with the deluxe version.   i am now trying to download the Premier version

 

ive tried restarting and deleting one year of the programs.   would like to keep the last 3-4 years on this laptop 

 

please help.   thank you, Craig
