If you're using Sage 50 on a regular basis, chances are you've come across this message at least once:
"Another user is already logged in" or
"Sage 50 is already logged in on this computer"
What's the worst part? You know that nobody else is online.
This doesn't necessarily mean Sage has broken. It's simply a sign that Sage thinks that the user's session is not closed, often because of an incorrect close, network lapse, or the background process didn't close correctly.
The good news is that, usually, this error can be corrected without reinstalling Sage or contacting supportthe only thing you need to do is if you understand what's leading to it.
Let's get it broken down properly.
sage customer support number (www.adhub.fi) 50 uses session and lock files to determine who is accessing the company's information. Once the system is completely shut down, these files are removed from the system automatically.
The error occurs when:
Sage closes unexpectedly
The system fails to stop or restarts.
The network connectivity is reduced
A user logs off incorrectly
Sage processes remain active in the background
In short, Sage believes a user session is still open--even when it isn't.
This error can be seen in these situations:
Sage is opening Sage following a power loss
Users can be switched on and off the shared system
Accessing Sage 50 in a multi-user setup
Files from the same company can be opened twice
Logging in after a force Windows update
Remote desktop sessions ending abruptly
Knowing the time it occurs helps you decide what you can fix it.
Before trying any technical fixes first do the obvious. But do it in a way that is safe.
Close Sage 50
Restart your system
Log back in, and try opening Sage again
A restart can clear hidden background processes more frequently than you'd expect.
You have Sage installed, but Sage will be running on multiple systems:
For other users, ask them to log out
Ensure no one has Sage either slowed down or is in idle
Restart the server in case it is needed.
Numerous "already logged in" errors are caused by open sessions that have been closed on a different machine.
Sometimes Sage appears to be closed, but she isn't.
Press Ctrl + Shift + Esc
Open Task Manager
Find:
Peachw.exe
PeachwServer.exe
PeachTree.exe
Choose each and click End Task
Once done, reopen Sage 50.
This will solve the issue for an enormous number of users.
This is the quickest solution when the error is refusing to disappear.
Sage creates lock-files within the company data folder. If these files remain after an improper exit Sage disables any new logins.
Typical location:
C:\Sage\Peachtree\Company
or the shared network drive in case you're using or a shared network drive if you're using multi-user access.
Within the folder of the company search for files that have extensions like:
.lck
.dta
.pta
.tmp
If Sage is not running anywhere you are able to clear these lock files.
Be careful:
Be sure to never delete the files if Sage is running or running on any other system.
After you delete them, reopen Sage and try logging in again.
In multi-user environments, Sage relies upon background databases. If these services cease to function and login errors are triggered, they will occur.
Press Windows + R
Type services.msc
Find:
Sage 50 Database Connection Manager
Sage 50 SmartPosting
Right-click - Restart
After restarting, wait for at least a minute before trying opening Sage once more.
This is particularly important to take into consideration if Sage installs on servers.
Sometimes, the error is due to mismatches with permissions instead of authentic logins.
Register as Admin (if it is possible)
Verify the rights granted to users.
Verify that the user's access isn't restricted to a single login
Check that the company's file isn't set to single-user mode.
If Sage lost its session while switching users, it could be holding the previous user's session.
Sage 50 is vulnerable to interruptions to network connections.
If your system is:
The Wi Fi network is used instead of the LAN.
Has unstable connectivity
Infrequently, the server will disconnect from it.
The login-related errors are likely to be more often.
Make use of wired LANs for Sage access
Avoid opening company files over VPN If it's not properly configured
Make sure the client and server systems are connected to the same network
Network drops trigger ghost sessions. Sage never receives the signal needed to close them.
To rule out network problems:
Copy the company's data to your local drive
Start it directly in Sage
If it is able to open without error message, the problem is related to the network, not data.
This test helps to determine the real cause instead of making assumptions.
This may sound like a simple concept, however permission blocks can result in misleading login mistakes.
Use the Right-click function to access Sage 50 shortcut
Select Run as an administrator
If this resolves the issue, adjust your system permissions to stop the problem from occurring again.

More recent Sage versions can be more prone to issues with session locks, particularly following Windows updates.
Check:
Your current Sage version
It is compatible with Windows version
Installing the latest software update frequently fixes recurring "already logged in" errors automatically.
Avoid quick fixes if:
Another user is genuinely at work
Sage is mid-process (posting or backing up)
The server hasn't been checked
Insisting on deletions when Sage is running can cause corruption of company information.
If you're uncertain, pause the situation and confirm before proceeding.
If none of the above methods will be successful, the issue could be:
Profiles of users with fraudulent information
Database of company damaged
Incorrect configuration of server and client
At this stage the time is when professional Sage assistance is suggested to help prevent data loss.
It's true that the Sage 50 "already logged in" error appears intimidating. However, in the majority of cases, it's just Sage still holding on to a session that didn't close properly.
Follow the procedure carefully:
Confirm no active users
Clear background processes
Secure files by removing them carefully
Stabilize the network
Once the issue is resolved The error is unlikely to recur in the event of another shutdown error.
Patience and clean exits go far in Sage.
