Hello VeniceBB,

Thank you for chiming in! I am so happy the suggestion mentioned worked for you! If you need anything else, the Community and I are here! Take care for now, 

Our research indicates that this is caused by Microsoft Windows Defender's real-time scanning, Aspen Ridge Condos. I’d like to share a quick solution to help you install the update.

Please know that QuickBooks updates require changes to the operating system registry, which Windows Defender closely monitors as part of its security protocols.

To address this, our engineers have developed a specialized tool that creates an exception in Windows Defender. This tells Windows to allow the necessary changes, allowing it to trust QuickBooks' modifications and ensuring smoother updates.

You can easily access and use this tool through the QuickBooks Tool Hub. Here's a step-by-step guide to help you:

1. Click the Cancel to stop the update and close the software.
2. Open the QuickBooks Tool Hub application.
3. Choose Installation issues, then click Add Defender Exclusion.
4. Make sure to restart your computer to apply the exemption
5. Reopen the software and start the update.
