This fix referenced by Support does not work when you are running Windows 10. After it failed me, I uninstalled TurboTax 2019 and then reinstalled it again. This time I received this error
Intuit.Spc.Esd.WinClient.Api.GeneralException:Access to the database file is not allowed. [ 1914.File name =?
If this happens to you, follow these instructions, it worked for me. This has to be an Intuit software problem regardless of what Support says because the user who solved this problem was trying to install a 2017 version of Turbotax from 2 years ago, yet if fixes the problem on a 2019 version of TurboTax. Get it together Intuit....
Please try the following steps:
1) Close TurboTax
2) Go to Task Manager, click on the "Services" tab. Try finding "IntuitUpdateServiceV4".
3) Right click on the service and click on "Stop" to stop the updater service.
4) Once the updater service is stopped, Go to "C:\ProgramData\Intuit" path and delete the "Common" folder.
5) After deletion, restart the Updater service i.e. Go to Task Manager, click on the "Services" tab. Try finding "IntuitUpdateServiceV4" ,right click on the service and then click on "Start" option.
6) Once the Updater service is started, try opening TurboTax again.
