This may seem trivial but it has worked for me to install Turbotax Premier 2018 and again with 2019 a few minutes ago and it has to do with Temporary Files and environment variables. If the installer just exits without doing anything after extracting the file, this could be your problem. Even if not, the fix is harmless and shouldn't mess up your computer:
Basically you want to change your Temporary files directory to C:\TEMP:
1.Create TEMP directory in root folder C (C:\TEMP) if it doesn't already have one.
2.Go to control panel using the search tool and look for the top right search box, Type “environment”, look up Advanced, look down click Environment Variables click yes if asked to make modification to your computer, look down the window that opens click on Environment Variables and change the TEMP and TMP Variables to your newly created or existing Temporary Files Folder (C:\TEMP), click OK.
3. Retry theTurboTax installer. Rebooting not required.
The only thing I can figure is the TurboTax installer doesn't handle custom temporary file folder locations well and if your computer has an imbedded system variable in the TEMP or TMP environment variables (indicated with a %) I don't think it resolves properly and doesn't handle the error well as there is nothing in the system or application logs.
Would love to know if this solved any of your problem(s).
