After turbotax did an update the program won't boot up. I get a windows box saying turbotax is not responding. I had been using this year's program with no problems until the latest update. I have tried re-installing the program but same result.
Did you completely uninstall the program before reinstalling it? https://turbotax.community.intuit.ca/replies/2647640
Here are some more specific instructions for Windows 7 installation. The screenshots are from 2016, but it should be similar to 2018: https://turbotax.community.intuit.ca/replies/2648062
