How to Resolve Sage 50 "Already Logged In" Error: A Practical Fix Guide That Actually Works
If you use Sage 50 frequently, chances have you've encountered this error at some point:
"Another user is already logged in" or
"sage support telephone number (http://support.roombird.ru) 50 is already logged in on this computer"
And the part that is most annoying? You can be sure that that nobody else is connected to your account.
This isn't a sign that Sage is damaged. It's an indication that Sage believes that that the user's session is active, which is usually the result of an incorrect termination, network break, or an ongoing process that didn't end properly.
The good news is that, in the majority of cases, this error is fixable without reinstalling Sage or calling supportand only if you understand what's leading to it.
Let's break it down in a way that is easy to understand.
What Does the "Already Logged In" Error Really Mean?
Sage 50 uses session and lock files for tracking who's accessing company information. When everything shuts down cleanly the files are deleted completely.
The error is apparent in the following situations:
Sage closes unexpectedly
The system fails to stop or restarts.
Drops in connectivity to the network
A user logs out with a mistake
Sage processes continue to operate in the background
In short, Sage believes a user session is still open--even when it's not.
Common Situations Where This Error Appears
This mistake is typically seen in one of these scenarios:
Sage is opening Sage after a power outage
Switching users in the system
Accessing Sage 50 when it is in a multi-user setup
Opening the same company's file twice
Logging into Windows after a forced Windows update
Remote desktop sessions ending abruptly
Knowing the time it's apparent can help decide how to correct it.
Step 1: Make Sure Sage Is Fully Closed Everywhere
Before you attempt technical fixes try the obvious. However, do it correctly.
Check on the Same Computer
Close Sage 50
Restart your system
Log back in, and try opening Sage once more
A restart stops hidden background processes more frequently than you'd like.
Check Other Computers (Multi-User Setup)
Should Sage can be installed on multiple systems:
Request other users to log out
Ensure no one has Sage reduced or is running inactive
Restart the server if necessary.
There are many "already logged in" errors result from a failed open session on another machine.
Step 2: Stop Sage Processes from Task Manager
Sometimes Sage looks like she's closed, but it's not.
How to Do It
Press Ctrl + Shift + Esc
Open Task Manager
Look for:Peachw.exePeachwServer.exePeachTree.exe
Select each one and click End Task
Once done, reopen Sage 50.
This action alone resolves the issue for a large variety of users.
Step 3: Check and Remove Temporary Lock Files
This is the quickest fix when the error refuses to disappear.
Sage creates lockable files within the data folder of the company. If these files remain in the folder after the exit process is not properly completed, Sage blocks any new login attempts.
Locate the Company Data Folder
Most common location:
C:\Sage\Peachtree\Company
or an shared network drive when you're using multi-user access.
What to Look For
In the folder for companies search for files that have extensions such as:
.lck.dta.pta.tmp
In the event that Sage is no where you are able to delete these lock files.
Wichtig:
Make sure you do not erase data while Sage is open across any platform.
After deleting them, restart Sage and try logging in.
Step 4: Restart the Sage 50 Database Service
In multi-user environments, Sage relies upon background databases. When these services fail to function when logged in, then login errors will occur.
How to Restart Services
Press Windows + R
Typeservices.msc
Watch out for:
Sage 50 Database Connection Manager
Sage 50 SmartPosting
Right-click - Restart
After restarting, take an hour before trying to open Sage once more.
This step is especially important if Sage was installed on servers.
Step 5: Check User Access and Company Permissions
Sometimes the error is due to permissions mismatches and not the actual logins.
What to Check
You can log in with the username Administrator (if you are able to do so)
Verify the access rights of users
You should ensure that users aren't bound to just one login
Verify that the company's data isn't configured to a single-user mode.
If Sage shut down while switching users, it may still be in the process of resetting the session for the previous user.
Step 6: Verify Network Stability (For Multi-User Systems)
Sage 50 is highly sensitive to disruptions in networks.
If your system:
Uses Wi-Fi instead of LAN
Has unstable connectivity
Sometimes, the server disconnects
The login-related errors are likely to be more often.
Practical Fixes
Use a wired Ethernet for Sage access
Avoid opening company files through VPN unless the VPN is properly configured
Make sure client and server systems are connected to the same network
Network drops can cause ghost sessions. Sage has no signal to close them.
Step 7: Open the Company File Locally (Test Method)
To rule out network issues:
The company's information file should be copied to your local drive
Open it directly within Sage
If it opens without the error, the problem is in the network, and not related to data.
This test helps pinpoint the exact cause rather than just guessing.
Step 8: Run Sage as Administrator
It may sound straightforward, but permission blocks could cause misleading login error messages.
How to Do It
Right-click Sage 50 shortcut
Select Run as an administrator
If this resolves the issue You can then modify the permissions on your system to prevent recurrence of the issue.
Step 9: Update Sage 50 to the Latest Version
Some older Sage versions may be vulnerable to session lock issues particularly following Windows updates.
Check:
Your current Sage version
Compatibility with your Windows build
Installing the latest update typically solves recurring "already logged in" errors automatically.
When Not to Delete Files or Force Fixes
Avoid quick fixes if:
Another user is genuinely signed in
Sage is a mid-process (posting and backing up, as well as restore)
The server hasn't even been checked.
Requiring deletions at a time when Sage is running can cause corruption of firm data.
If you're not sure, pause and check before taking action.
What If the Error Still Persists?
If none of these methods result, the issue may include:
Profiles of user profiles that are fraudulent
Data of the company has been damaged
Incorrect configuration of the server client
At this stage Professional Sage support is recommended to ensure that data is not lost.
Final Thoughts
"The Sage 50 "already logged in" error is a bit scary, but in the majority it's simply Sage holding onto a session which wasn't closing properly.
Do it carefully:
Confirm no active users
Clear background processes
Remove the lock files with care.
Stabilize the network
After being fixed it's rare for the error to return unless there's another improper shutdown.
A clean and tidy exit can go an extremely long way in Sage.
