Error 1603 - QuickBooks - Intuit - Windows 10
I had this error trying to install on Windows 10. The solution I thought of, not from an online support source, and found to work was to start the installation process by first changing the properties of the installer and make it Windows 7 compatible. That got me past error QuickBooks error 603 on Windows 10.
Right click the file then select properties. Click compatibility, check the box for compatibility mode, change the OS version .
Save, and then run the installer again. I also right click and select run as Administrator when starting the QuickBooks install software.
