See if the TurboTax Help article Troubleshoot installation and running TurboTax for Windows is helpful. 

If not, feel free to post back with more information.  For example, you might describe which version of TurboTax you’re trying to install, whether you’re using Windows or Mac, and, if you’re using Windows, which version you have installed.
