I have asked ChatGPT, Copilot about this error and have tried to do step by step: using Quickbooks Tool Hub, reinstalling .Net framework 3.5 and 4.8 on Windows 11, turning off firewall and virus program ...), but all this can't fix this error. 

I also tried to install Quickbooks Desktop 2024 on Windows 10 on another laptop but it still receive the same error.

I have just downloaded QuickBooks Premier Professional Services Edition 2024 Trial version. After installing it and run (no need Begin Activation step), Event Viewer still shows the error event ID 4:

 An unexpected error has occured in "QuickBooks":
MainFrame must be already created by now as this dll is demand loaded

And when I clicked the button "BUY NOW", the window shows the error: HTTP 404 Not Found

I can't add my licence from Trial Version

Event Viewer also shows another error ID 1000: Application Crashing Events
