Troubleshooting the "Unable to Obtain License 5677" Error The error "Unable to Obtain License 5677 . License Request For" (often accompanied by error 5884) typically occurs in environments running Progress OpenEdge or applications using ActiveX Controls. It is fundamentally a version mismatch or a registration failure within the Component Object Model (COM) handle. Core Causes of Error 5677
Understanding why this error triggers is the first step toward a resolution. The most common triggers include:
ActiveX Version Mismatch: The most frequent cause is when a machine has an older version of an ActiveX Control than what the upgraded application requires.
Uninitialized Handles: In Progress programming, the error may occur if a COM-HANDLE was never initiated or was disabled before a specific procedure (like RUN viewreport) was triggered.
Corrupted Licensing Service: Issues with background licensing services, such as the FlexNet Licensing Service, can prevent the software from verifying the request.
Environmental Conflicts: Environment variables pointing to the wrong software version or configuration file can lead to failed license checkouts. Step-by-Step Solutions 1. Update ActiveX Controls
If you have recently upgraded your software, the application may be trying to call a newer version of an ActiveX component that isn't registered on your current machine.
Locate the specific ActiveX control required by your software.
Reinstall or register the newer version of the control manually using regsvr32 if necessary. 2. Verify COM-Handle Initialization
For developers or system administrators managing Progress-based applications:
Ensure that the COM-HANDLE is properly initiated in the calling procedure.
Check for any DELETE OBJECT statements that might be prematurely clearing the handle before it is used. 3. Check License Configuration Files
Sometimes the license file itself is the culprit, especially after an upgrade.
Progress Users: Check the progress.cfg file. Ensure it is not an expired evaluation copy.
Version Check: Ensure you aren't trying to use a license addendum for the wrong version (e.g., trying to use an 11.3 update on an 11.2 installation). 4. Firewall and Network Connectivity
If your software uses a network-based license manager (like COMSOL or Citrix), ensure that:
"Unable to set com-handle property (5677)" is a common technical issue primarily associated with Progress OpenEdge
and applications built on its framework. It typically occurs when an application tries to interact with an external component (like an ActiveX control or a Microsoft Office product) and fails to establish a valid connection. 🛠️ Root Causes & Solutions
This error is rarely a "bug" in the software itself but rather a configuration or environment mismatch. 1. Version Mismatch (Most Common) The application is looking for a specific version of an COM control
that is either missing or has been replaced by a newer/older version. Progress Community
Ensure you have the exact version of the component required by your software (e.g., specific versions of mscomctl.ocx 2. Registration Issues
The system cannot find the handle for the object because the component isn't registered in Windows. Progress Community Manually register the component using in an elevated Command Prompt (e.g., regsvr32 your_component.ocx 3. Permission Blocks
The application does not have the necessary administrative rights to "hook" into the external process or set its properties. Try running the application as an Administrator 4. Application Logic Error (For Developers) If you are a developer, this error often appears when: Progress Community A variable (handle) was never initialized. A sub-procedure disabled the handle before it was called.
You are trying to access a property or method that doesn't exist for that specific object. 📋 Quick Troubleshooting Checklist Check Recent Updates:
Did you just install a new version of the app or a Windows Update? Roll back or update the component. Verify Office Bit-Version:
If the software interacts with Excel/Word, ensure the "bitness" (32-bit vs 64-bit) of Office matches what the application expects. Re-register COM: Use the Command Prompt to re-register the relevant Repair Install:
Running a "Repair" on the main application often restores missing registry keys. To help you get a more specific fix, could you tell me:
are you using when this happens? (e.g., a specific ERP, medical software, or custom business app)
triggers the error? (e.g., opening a report, exporting to Excel, or just launching the program) Did this start after a Windows Update

The error "Unable To Obtain License 5677" typically occurs in environments using OpenEdge or Progress software, often appearing alongside error 5884. This specific error message, "Unable to set com-handle property (5677)," usually indicates a version mismatch with an ActiveX Control required by the application. Core Cause
The primary reason for this failure is that the ActiveX Control version currently installed on the client machine is older than what the upgraded application requires. This prevents the software from properly initializing its component handles. Troubleshooting and Fixes To resolve this error, follow these steps:
Update ActiveX Controls: Install the specific version of the ActiveX Control required by the current application build.
Verify Installation Permissions: On Windows machines with User Account Control (UAC) enabled, ensure you run product registration or installation tools explicitly as an Administrator.
Check Environmental Services: For related license manager issues, some users find success by setting the Sentinel LDK License Manager service startup type to "Automatic (Delayed Start)" to ensure all system resources are ready before the service attempts to pull a license.
License Path Configuration: Ensure your system's PATH variable includes the correct binary sub-directory of your software installation so the system can locate necessary license files like register.ini. Related Variations
A similar code string (mgls_errno 203) is often reported alongside this error, which sometimes points toward driver conflicts (such as older HASP drivers) or issues with specific features like Xpkglayout_c. If these basic fixes do not work, consult your licensing administrator to check if the specific product tag or version has enough available seats or has expired.
Are you seeing this error after a recent software upgrade, or did it start happening spontaneously on an existing installation?
The Autodesk error "Unable To Obtain License 5677" generally indicates a communication failure between the software and the license server, often caused by expired credentials, firewall blocks, or a corrupted login cache.

"Unable To Obtain License 5677. License Request For [Feature Name] Failed. The License Server Manager Could Not Be Reached Or The Feature Is Not Available." Common Causes & Meanings
Error 5677: This specific code often refers to a version mismatch or a network communication failure between the client machine and the license server [1, 2].
Feature Not Found: The "License Request For..." section usually lists a specific tool or plugin name that your current license file does not include [3].
Server Down: The licensing service (e.g., lmgrd.exe) may have stopped running on the host server [2]. Quick Fixes
Check the Server Status: Ensure the license server is powered on and the licensing service is actively running.
Verify the License Path: Check your system environment variables (like ADSKFLEX_LICENSE_FILE or LM_LICENSE_FILE) to ensure they point to the correct server IP or hostname [4].
Firewall Settings: Ensure ports 27000-27009 (default for FlexLM) are open on both the server and your local workstation [2, 4].
Update License File: If you recently updated your software, you may need a new license file that includes the updated "feature" codes for the newer version [3]. To help you narrow this down, could you tell me:
