QB2024_Core_R19R20_msp.dat cannot confirm publisher.

Hey there, @EC_Eric.

How are you doing today? I hope all is well. 

Since the QuickBooks Tool Hub and exceptions didn't work, I recommend manually installing the Intuit Certificate. This tells Windows that Intuit is a trusted publisher so it stops the "instant delete" behavior.

Here's how: 

1. Close QuickBooks.
2. Open File Explorer and go to: C:\Program Files\Intuit\QuickBooks 2024 (or your installation folder).
3. Find qbupdate.exe, right-click it, and select Properties.
4. Go to the Digital Signatures tab.
5. Select Intuit, Inc. from the list and click Details.
6. Click View Certificate, then select Install Certificate.
7. Follow the wizard: Select Local Machine > Place all certificates in the following store > Trusted Root Certification Authorities.
8. Finish the wizard, restart your computer, and try the update again.

That should do the trick. For more information about this process, along with additional troubleshooting steps, check out Fix error 15XXX when updating QuickBooks. 

Please let me know if you have any questions or concerns. I'm always happy to lend a hand. Take care!
