The engineering team looked into the issue and found that the issue which was fixed in early feb came back again in the mid feb release. The engineering team is working on it to provide a solution as a download by end of this week.
What you can try alternatively try is: Download a early Feb installer for Turbotax 2018 which has this fix included. You can download it from
https://intuitglobal.intuit.com/downloads/CanadaTax/2018/dls/TurboTax2018_Build3007.exeand see if it helps in installing the product.
The application ones booted will automatically find a update and it will patch you to the latest updates.
Can someone please try and let me know if this fixes the issue?
Sorry for the inconvenience caused and hope it helps in solving the problem.
