Hi there, @bcgoimec.
I appreciate your efforts in performing some troubleshooting steps to get this resolved and providing the error code that you're getting. Allow me to provide additional information to get this resolved.
Error code -6190, 816, means that another user is logged in to the company file in single-user mode. It can also be a mismatch between the transaction log file (.tlg) and the company file (.qbw). To get this fixed make sure to have one PC/Server to host the company files. Here's how:
- Press F2. The Product Information window opens.
- Find Local Server Information. Hosting should be turned off.
Once done, try to rename the.ND and.TLG files and run the Database Server Manager from the QuickBooks Tools Hub again. This will allow QuickBooks to access a company file in a network or multi-user environment.
You can also, open a sample company file locally installed on a workstation. This way, you can test if the problem is within your company file or the QuickBooks application. If a sample company file does not open and instead returns an error, it is an indication that the QuickBooks installation is damaged and should be repaired.
- In the No Company Open window, select Open a Sample File, then choose from the list of sample company files.
- If the sample file opens, proceed to solution 4. If the sample file returns the same error message, repair your QuickBooks installation.
