Windows 10 updates wouldn't work to open existing Desktop Premier 2024; I deleted the Application; now I can't get program reinstalled!

After Windows 10 updates problems I finally solved, I still couldn't get rid of the "Failed to Install Update - Error 1603 - Fatal Error during install." 

 

Because of Turbotax's shortened hours, I couldn't reach them.  I then stupidly the Application; now I can't get program reinstalled! I have .taxfile for 2024, but it doesn't seem to help to reinstall the program.

 

I purchased Premier from Costco but can't remember how Turbotax helped me install it.

 

NEED HELP!
