Methods for resolving the Sage 50 Unable to Open Company File problem Before you begin troubleshooting, ensure sure you have a backup of your data. Let’s take a look at each technique for resolving the Sage 50 Unable to open company file problem one by one:

Method 1: Log in to Sage as an administrator:

Shut off your Sage 50 software first. After that, right-click the Sage 50 icon.

Select “Run as an Administrator” from the drop-down menu.

 After that, attempt to access the company file.

 Add permissions to the data and move it to a new location on the hard disc.

 Add everyone to the user permission settings by copying the.SAI and.SAj folders to the root of C Drive.

 Ascertain that the.SAJ folder will not include any hidden directories or files.

 Finally, attempt to reopen your company data file.

Method 2: Incorrect Icon: First, make sure you’re using the correct programme.

If you’re using a programme from the Taskbar, you’ll need to in-pin it (right-click and select “Unpin from Taskbar” from the menu). After that, pin a fresh version (perform a right-click on the Desktop shortcut and then pin to the taskbar).


On a network, Method 3: MySqld.exe is locked in Task Manager.

Make sure that all Sage users are signed out. On the server, go to Task Manager and make sure that Show processes from all users is checked. After that, go to the Processes tab and terminate all Mysqld.exe processes. Attempt to reopen the company files on the workstations after completing the complete process.

In a Standalone Situation

Ensure that the Sage 50 programme is shut down. Then, go to Task Manager and start it up. End all Mysqld.exe processes after confirming that the display process from all users is chosen.

Method 4: Look for any missing or hidden folders or files:To begin, go to the place where your company file is stored. Look for the.SAJ folder and double-check that it has all necessary files and directories. 

Disable Antivirus and Real-Time Scanners (method 5):

Disable your antivirus software. If you have many security/antivirus programmes, remove them all until you only have one left. If your system is set up with Microsoft Security Essentials, perform the following:Disable auto protection because McAfree requires both real-time scanning and a firewall. Disable real-time protection.

  •  If neither is deactivated, McAfree will prevent the conversion from 2017 to 2018.
  •  If you’re using auto backup software to back up your company’s data, make sure it’s turned off. Examine the event logs in Windows Event Viewer.Select “Run as an Administrator” from the right-click menu on the Sage 50 icon. Attempt the converting procedure once more. Re-enable your security software when the conversion is complete.
