I am not able to open Quicken after upgrading it. Please help

[Norahbailey]

Your Quicken will not open if it's not installed correctly or if you install it in the shared drive. During the installation process, you must select your computer's hard drive to save the Quicken installer files. To fix the issue, primarily, you must restart your computer and then try to reinstall the update patch following the proper instructions. If still, the problem exists, then press and hold ctrl+shift keys and double click Quicken icon. Keep holding the ctrl+shift keys until you see a black screen; if it occurs, that means there is a problem with your data file. Now click the file tab, click file operations, and then select validate and repair. Further, checkmark Validate file and then click Ok. Hopefully, you resolved the issue, and now your Quicken is operating.
