Get your taxes done using TurboTax

I have experienced a similar problem. I have installed TurboTax Business 2021 on two laptops with Windows 10. After the installation, I opened the program. It attempted to start, but ultimately didn't. I have spent more than three days to install and uninstall the TurboTax Business 2021.  It still doesn't work.

Can someone help me to solve this technical problem?

I have been using TurboTax for individual and Business for about 20 years. This is the first time I can't open the application.
