Welcome to the community.
The 2009 product has been retired under Subscription. Therefore, if you ever upgraded, crossgraded, or had the product under Subscription at any point, then you are likely unable to install and activate this software. If it was upgraded or fulfilled to a later version under Subscription, you should still be able to install and activate your most recent version.
Otherwise, see my invalid serial number link below.
Your product key is most likely 057A1.
If you need further assistance, you might contact your VAR or philip.s here in the community.
