Upgrade to Quickbooks desktop pro 2023 with windows 10. Now everything is messed up.

Hello there. I'll make sure to fix your QuickBooks Desktop (QBDT) installation error.

Let's run the repair tool for QBDT for Windows so you can fix the installation error you have and get back to business in no time.

When you get an error when you use, install, or update QuickBooks, our tool hub can help fix the common company file error right away. To do this, you first need to download (if you haven't already) the QuickBooks Tool Hub. For the best experience, we recommend you use Tool Hub on Windows 10, 64-bit. Here's how:

1. Close QuickBooks.
2. Download the most recent version (1.6.0.3) of the QuickBooks Tool Hub. 
3. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). Note: If you've installed Tool Hub before, you can find out which version you have. Select the Home tab. The version will be on the bottom.
4. Open the file you downloaded (QuickBooksToolHub.exe).
5. Follow the on-screen steps to install and agree to the terms and conditions.
6. When the installation finishes, double-click the icon on your Windows desktop to open the tool hub.

Once done, run the Quick Fix my program tool to shut down any open background processes QuickBooks uses and run a quick repair on your program. Here's how:

1. In the QuickBooks Tool Hub, select Program Problems.
2. Select Quick Fix my Program.
3. Start QuickBooks Desktop and open your data file.

In case the error persists, continue troubleshooting by running the QuickBooks Install Diagnostic Tool. For the step-by-step guide, please refer to this article: Repair your QuickBooks Desktop for Windows.
