I don't know if I am replying in the correct thread. I upgraded/ to a new windows 11 Pro desktop last November because I read Turbotax would not support windows 10 in 2025. I just downloaded the Turbotax 2025 Home and Business. I bought the activation code @ Costco. It installs but will not open. I just get a blank error. I tried uninstalling, turning off antivirus and firewall and installing as administrator. My new desktop meets all of the requirements. Does anyone know what the problem could be? It should not be this difficult to open up. It wont open to allow me to put in the activation code.
