A month ago I upgraded to QB Enterprise (I love it!). I know that Enterprise allows me to open two company files at once. However, even if I only have one company file open, I am getting the attached error message. It is persistent.
I appreciate you sharing detailed information and screenshots of the error message you are encountering with your upgraded QuickBooks Desktop (QBDT) Enterprise version, PattiB.
To resolve the error message you are encountering, I recommend opening the Task Manager and selecting End Task to refresh QuickBooks.
Here's how:
Open Task Manager on your system.
Locate the QuickBooks application and right-click on it.
Select the End Task option.
Please see the sample screenshot below for reference:
After that, please re-launch your QBDT Enterprise.
Please feel free to reply below with any questions or updates on your progress.
