Does anyone know why (blue screen shut downss ) with this as the string An unexpected error has occured in "QuickBooks Desktop Pro Plus 2020": Connection String:CON=QBC

A damaged system can be the caused of this error, Carol Lane.

 

Let's determine this further by running the Tool Hub. I'll show you how:

 

  1. Close your QuickBooks file.
  2. Download the QuickBooks Tool Hub file, and then save it.
  3. Open the downloaded file (QuickBooksToolHub.exe).
  4. Follow the on-screen instructions to install the file.
  5. Once installed, open the tool hub by clicking the icon twice.

 

Then, let's use the Diagnostic Tool.

 

  1. In the Tool hub, select Installation Issues.
  2. Select QuickBooks Install Diagnostic Tool.
  3. Once done, restart your computer.

 

Afterward, let's open your QuickBooks file again. If you still get the same error, I would suggest reaching out to an IT expert. They're the best support that can verify the issue further and fix it.

 

I'm just here if you have other concerns with your file.
