Hi Smith,

When the QuickBooks company file moved from one machine to another or to another drive the permission properties will be affected, and the file integrity needs to be checked.

Resolution:

• Open the location of the company file.
• Right click on the file and select Properties.
• Click on the Security window.
• Select all the users one by one and provide Full Control by clicking on the check box next to allow.
• Click on the Advanced button and navigate to the Owner tab.
• Change the owner to the Administrator or to the person who has logged in to the system.
• Click on OK to close the Advanced Security Settings and OK again to close the file properties window.
• Please open the following location to download and install the QuickBooks Connection Diagnostic Tool.
• Click the following link to download the diagnostic tool – https://community.intuit.com/articles/1284324-quickbooks-connection-diagnostic-tool.
• Enter your e-mail address and check the option I agree to the terms and conditions and click on Download Tool button.
• Once downloaded, double-click on the file to install the tool.
• Click Start > All programs > QB connection diagnostic tool > QB connection diagnostic tool on your Windows operating system.
• Under Test Connectivity, click on Browse and select the company file and click on Test Connectivity.
• If you see File Open successful (all Advanced statuses have green check marks) your network connection is working fine, and you should be able to open the file.
• Try opening the QuickBooks company file again.

I hope this helps.

What I did was that I googled this error and found a solution on Medium.com article which I will leave a link so that you can read the detailed solution.
