When trying to install Quicken, the following error can occur:
Error 1913. Could not update the ini file C:/ProgramData/Intuit/Quicken/Config/Quicken.ini
This error can occur if a previous version of Quicken was uninstalled, but not completely removed.
To resolve the error, you must use the QcleanUI tool to remove all Quicken products and any shared folders from the computer, and then try installing Quicken again.
