Thanks for sharing your concern with us, Frank90.

We can fix the character error you're getting after installing the QuickBooks Desktop Premier 2019 by downloading the QuickBooks Tool Hub. This tool is designed to automatically diagnose and fix issues within the software. Below are the instructions on how to do it:

2. Download the most recent version (1.4.0.0) of the QuickBooks Tool Hub. Save the file somewhere you can easily find it.
3. Open the file you downloaded (QuickBooksToolHub.exe).
4. Follow the on-screen steps to install and agree to the terms and conditions.
5. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.
6. Once the  QuickBooks Tool Hub is open, select Program Problems.
7. Select Quick Fix my Program.
8. Start QuickBooks Desktop and open your data file.

To ensure the components are properly updated, please restart the computer after running the tool.

If this doesn't work, we can try using the Rebuild Data tool in QuickBooks Desktop. This tool is used to fix any possible data damage within your company file. Let me show you the steps on how to perform this below:
