Hi there, @Bec11.
We can run the diagnostic tools from the tool hub if you encounter error 1603 when installing QuickBooks Desktop.
Here's how to download QBDT Tool Hub:
- Close QuickBooks.
- We recommend you download the most recent version (1.4.0.0) of the QuickBooks Tool Hub. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). Note: If you've already installed Tool Hub before, you can find out which version you have. Select the Home tab. The version will be displayed on the bottom right or you can select About to view the version.
- Open the file you downloaded (QuickBooksToolHub.exe).
- Follow the on-screen steps to install and agree to the terms and conditions.
- When the install finishes, double-click the icon on your Windows desktop to open the tool hub.
After that, you'll need to start using the QBDT Diagnostic tool. Feel free to visit this article for more instructions: Fix Error 1603 when you install QBDT.
Please don't hesitate to leave a reply if you have additional concerns in QBDT. We're always here to help.
