This article lists log file locations for all ProfileUnity client and server components. Each entry includes the log path, default logging level, and the executable it belongs to. Applies to ProfileUnity 6.8 and later.
ℹ️ Logging modes
ProfileUnity components use one of three logging levels: Fatal logs crash-level errors only — Info logs normal status messages — Debug logs all diagnostic data. Components set to Fatal must be changed to Debug before collecting logs for a support case.

Client-Side Log Locations
All client-side logs are written on the endpoint running the ProfileUnity client. For non-persistent VDI, redirect the log path to a network share so logs survive session termination.
Change the client log path to a UNC share on non-persistent machines. Logs written to local temp paths are lost when the session terminates.
| Component | Log Path | Mode | Executable |
|---|---|---|---|
| Client (Logon) | %temp%\ProfileUnity | Fatal | LwL.ProfileUnity.Client.exe |
| Client License Service | %systemroot%\Temp\ProfileUnity\clientlicensingservice_%domain%_%username%_%date%_%time%.log | Info | LwL.ProfileUnity.Client.LicenseService.exe |
| Profile Service | %systemroot%\Temp\ProfileUnity\*date**time*_lwl_profile_service.log | Debug | LwL.ProfileUnity.Client.ProfileService.exe |
| UIA (UserApp) Service | %systemroot%\Temp\ProfileUnity\*date**time*_lwl_userapp_service.log | Debug | LwL.ProfileUnity.Client.UIAutomationService.exe |
| Elevation Service | %systemroot%\Temp\ProfileUnity\*date**time*_lwl_elevation_service.log | Debug | LwL.ProfileUnity.Client.ElevationService.exe |
| Command Service | %systemroot%\Temp\ProfileUnity\cmdservice_%domain%_SYSTEM_*date*_<RND>.log | Fatal | LwL.ProfileUnity.Client.CmdService.exe |
| FlexApp DIA | %temp%\ProfileUnity\client_FlexAppDIA*.log | Debug | LwL.ProfileUnity.Client.FlexAppDIA.exe |
| Startup.exe | C:\Windows\Temp\ProfileUnity | Fatal | LwL.ProfileUnity.Client.Startup.exe |
| Logoff.exe | %temp%\ProfileUnity | Fatal | LwL.ProfileUnity.Client.Logoff.exe |
Follow: How to Change Enhanced Client Logging to Debug Mode
Modify the file below and change the logging level to Debug:
C:\Program Files\ProfileUnity\Client.net\LwL.ProfileUnity.Client.CmdService.exe.config
FlexApp One Log Locations
FlexApp One log files are written to the following paths on the endpoint. All three locations should be collected when troubleshooting FlexApp One application issues.
| Location | Log Path | Notes |
|---|---|---|
| User Temp | %temp%\ProfileUnity | User-context FlexApp One logs. Accessible without elevation. |
| System Temp | %windir%\Temp\ProfileUnity | System-context FlexApp One logs. Admin rights required to access. |
| Intune Deployments | %programdata%\Microsoft\IntuneManagementExtension\Logs | Additional logs captured when FlexApp One is deployed via Microsoft Intune. |
The FlexApp One Engine supports a CLI flag to specify a custom log file output path. This is useful for redirecting logs to a central share or a fixed location for non-persistent environments. Contact Liquidware Support or refer to the FlexApp One Application Command Line Arguments documentation for details.
The ProfileUnity Diagnostic Tool can also be used to collect FlexApp One logs. When running on the FlexApp Packaging Console or in a standalone FlexApp One environment, right-click the tool and select Run as Administrator. The tool will create a zip file in %TEMP% containing logs and system information.
FlexApp Packaging Console:
C:\Program Files (x86)\Liquidware Labs\FlexApp Packaging Console\Diagnostic\LwL.ProfileUnity.Client.Diagnostic.exe
FlexApp Packaging Automation:
C:\Program Files (x86)\Liquidware Labs\FlexApp Packaging Automation\punc\LwL.ProfileUnity.Client.Diagnostic.exe
FlexApp Packaging Console (FPC) Logs
The FPC always runs in Debug mode. No configuration change is needed.
| Component | Log Path | Mode | Executable |
|---|---|---|---|
| FPC | %temp%\fpc | Debug | FlexAppPackagingConsole.exe |
Management Host Log Locations
The following logs are located on the ProfileUnity server.
| Component | Log Path | Mode | Executable |
|---|---|---|---|
| ProfileUnity Console | C:\Program Files (x86)\Liquidware Labs\ProfileUnity\logs | Info | ProfileUnity.exe |
| FlexDisk Service | C:\Program Files (x86)\Liquidware Labs\ProfileUnity\FlexDisk\flexdisk.log | Info | LwL.ProfileUnity.FlexDiskService.exe |
| License Server | C:\Program Files (x86)\Liquidware Labs\ProfileUnity\License Server\Logs | Info | ProfileUnity.LicenseServer.exe |
| MongoDB | C:\Program Files\MongoDB\log\mongo.log | Info | mongod.exe |
Log in to the Management Console, navigate to Administration > Service Logs, change the Level of Logging to Debug, and click Update.
