Let’s get rid of the Script Error pop-up, @David_Alison.
Message prompts like this occurs when QuickBooks tries to connect to Internet Explorer but is blocked by webpage issues. You need to configure QBDT’s default browser settings to stop it from happening.
Once done, try launching QuickBooks again. You also have to make sure that the program is updated to the latest release to fix minor issues.
