@Leverh02 have you tried restarting your computer and trying the install again?

Yes - several times.

@Leverh02 this issue point to a problem with Windows.

Error code 1618 during a Quicken installation typically means that another installation process is already running on your system. This is a Windows Installer error, not specific to Quicken, and it’s officially known as ERROR_INSTALL_ALREADY_RUNNING.

Here are some things to try to resolve this issue:

Check for Active Installers
- Press Ctrl + Shift + Esc to open Task Manager.
- Look for any processes like msiexec.exe or other installer-related tasks.
- If found, right-click and select End Task.
Run the Quicken Installer Again
- Make sure no other installations or updates are running in the background.
Use a Clean Boot (if needed)
- This starts Windows with minimal drivers and startup programs:
- Press Windows + R, type msconfig, and hit Enter.
- Under the Services tab, check Hide all Microsoft services, then click Disable all.
- Go to the Startup tab and click Open Task Manager. Disable all startup items.
- Restart your PC and try installing Quicken again.
Ensure Windows Installer Service is Running

Press Windows + R, type services.msc, and press Enter.
Find Windows Installer, right-click, and choose Start (or Restart if already running).

@Leverh02 happy to hear your issue is resolved. I have found that a most installation errors with Quicken stem from a Windows error or configuration issue.
