Global excludesGlobalExcludesConfigFile="filename.INI"Use this setting to apply global exclusions across all Flex config files. Specify the absolute or relative path to your global excludes Flex config file here. If a relative path is specified, it is resolved against the General folder.
Diagnostics: Collect performance logPerformanceLogFilename="perflog.blg"
PerformanceCounter1="..."
PerformanceCounter2="..."
...
PerformanceCounter10="..."
Enable this setting to collect a binary performance log while DEM is performing a path-based import. This log can be subsequently viewed and analyzed in Windows Performance Monitor. If only the performance log filename is configured, the following performance counters are collected.
  • \Processor(_Total)\% Processor Time
  • \System\Context Switches/sec
  • \System\Processor Queue Length
  • \PhysicalDisk(_Total)\Avg. Disk Queue Length
  • \PhysicalDisk(_Total)\Disk Reads/sec
  • \PhysicalDisk(_Total)\Disk Writes/sec
  • \PhysicalDisk(_Total)\Avg. Disk sec/Transfer
  • \Memory\% Committed Bytes In Use
  • \Memory\Page Faults/sec
If performance counters are configured, only the configured counters are collected.

Diagnostics: Log CPU and I/O statistics for registry importLogProcessStatsForRegistryImport="1"Set the value to 1 to log CPU and I/O statistics for registry import
Diagnostics: Log CPU consumptionCpuConsumptionLimit="threshold"Enable this setting to log CPU consumption of other processes that were running while DEM performed a path-based import or export. CPU usage is logged for each process that consumed more CPU than the configured threshold (in milliseconds)
Diagnostics: Log slow callsCallTimeLimit="threshold"Enable this setting to configure how long certain calls can take (in milliseconds) before a warning is logged
Diagnostics: Enable verbose logging for ADMX-based settings, application blocking, privilege elevation and Horizon Smart PoliciesAdmxLogging="1"Set the value to 1

Override previously hidden drive letters (requires DEM 2203 or later)OverrideHideDrives="1"Set the value to 1 to override the existing Hide Drives Settings.
Custom Commands
Custom command to run before path-based importPreExecutionCommand="command"Specify the command to run
Custom command to run after path-based import (requires DEM 2111 or later)PostLogonCommand="command"Specify the command to run
Custom command to run before path-based export (requires DEM 2111 or later)PreLogoffCommand="command"Specify the command to run
Custom command to run after path-based export (requires DEM 2111 or later)PostLogoffCommand="command"Specify the command to run
Expand environment variables in custom command settings (requires DEM 2203 or later)ExpandCustomCommands="1"Set the value to 1
Custom commands as SYSTEM
Custom command to run before path-based import (requires DEM 2303 or later)PreLogonCommandAsSystem="command"Specify the command to run. This command is executed before its PreExecutionCommand user counterpart.
Custom command to run after path-based import (requires DEM 2303 or later)PostLogonCommandAsSystem="command"Specify the command to run. This command is executed after its PostLogonCommand user counterpart.
Custom command to run before path-based export (requires DEM 2303 or later)PreLogoffCommandAsSystem="command"Specify the command to run. This command is executed before its PreLogoffCommand user counterpart.
Custom command to run after path-based export (requires DEM 2303 or later)PostLogoffCommandAsSystem="command"Specify the command to run. This command is executed after its PostLogoffCommand user counterpart.
Expand environment variables in custom command settings ran as SYSTEM (requires DEM 2303 or later)ExpandCustomCommandsAsSystem="1"Set the value to 1
Use built-in registry parser (requires DEM 2206 or later)EnableRegParser="1" Set the value to 1 to use the built-in registry parser instead of regedit.exe or reg.exe to import registry settings.
License location (requires DEM 2206 or later)LicenseLocation="path to FlexEngine.lic"Set the value to the fully-qualified absolute path of the license file, to override the default location where the DEM agent expects to find its license. For example, LicenseLocation="C:\Users\test\Desktop\License.xml" By default, the DEM agent finds its license in the General\FlexRepository\AgentConfiguration\License.xml file on the config share.
Disable import and export (requires DEM 2209 or later) DisableImportExportForGroupsOfUsers="UserGroupNames" DisableImportExportForGroupsOfDevices="DeviceGroupNames" Specify a comma-separated list of group names to disable import and export for certain users or devices. For example, DisableImportExportForGroupsOfUsers="UserGroup1,UserGroup2" DisableImportExportForGroupsOfDevices="DeviceGroup1,DeviceGroup2,DeviceGroup3"
Secondary logging on Horizon (requires DEM 2312 or later)MaximumHorizonLogFileSize="1024" Enable this setting to specify a different maximum size for secondary logging on Horizon.By default, the secondary log files are recreated when they reach a size of 512 KB. To disable creating secondary log files, set the maximum size to 0.
Delegate pending DirectFlex exports to child process (requires DEM 2312 or later)DelegatePendingExports="0" PendingExportsTimeout="timeout" If a DirectFlex import for an App-V 5 application has taken place during the session, logoff processing of pending DirectFlex exports is delegated to a child process by default. This prevents issues that sometimes occur when performing an App-V 5 export during logoff.
  • Setting DelegatePendingExports to 0 - never delegates pending DirectFlex exports (this might cause pending App-V 5 exports to fail).
  • Setting DelegatePendingExports to 1 - always delegates pending DirectFlex exports, regardless of whether an App-V 5 import was performed during the session.
By default, the overall DEM logoff processing will wait for 120 seconds for the delegated export to complete. This timeout can be modified by configuring PendingExportsTimeout="timeout".
Ignore computer name for run-once flag files (requires DEM 2412 or later) RunOnceIsComputerAgnostic="1" This setting is applicable only when the Run Once option is enabled for the user environment settings.
When you enable this setting, the DEM agent checks if any flag file exists for a user environment setting, regardless of the computer name. If the flag file already exists for the user, a "fallback" flag file will not be created.
Note: This setting has a similar behaviour compared to the existing runOnceSpecial="1" attribute. However, if you are using the runOnceSpecial attribute, it creates a "fallback" flag file based on the computer name.

DirectFlex compatibility fix: Change process exit logic (requires DEM 2412 or later) DirectFlexHookProcessExit="0" In certain cases, DirectFlex logic might interfere with the exit of DirectFlex-enabled UWP apps. As a result, no DirectFlex export is performed at that time, as the process does not fully exit.
Set this value to 0 to change the process exit logic.
Use workaround for default applications and file type associations (requires DEM 2503 or later) UseUCPDWorkaround="0" Previously, a separate configuration for the UCPD.sys workaround was required to correctly process default application settings and file type associations. Starting with Dynamic Environment Manager 2503, the workaround logic is incorporated into the product to provide a seamless and reliable solution for managing default browser and PDF FTA settings on Windows systems. By default, this feature is enabled.

Configure UseUCPDWorkaround="0" to revert to the original behaviour.
