Set Environment Variable
UiPath.Core.Activities.SetEnvironmentVariable
Use this activity to set an environment variable, providing the name and the value for it. If the variable does not already exist, it will be created automatically.
Note:
On Windows, this activity sets User Environment Variables. On cross-platform projects, it sets Process Environment Variables. Understanding how environment variables are loaded from Machine and User levels into the Process scope is important for interpreting the Windows and cross-platform behavior differences of the Get Environment Variable and Set Environment Variable activities.
Properties
Common
- DisplayName - The display name of the activity. This field supports only
StringsorStringvariables.
Input
- Name - The name of the new environment variable. This field supports only
StringsorStringvariables. - Value - The value of the new environment variable. This field supports only
StringsorStringvariables.
Misc
- Private - If selected, the values of variables and arguments are no longer logged at Verbose level.
Platform-specific behavior
Windows environment
When running on Windows (default configuration):
- Environment variables are set at the User level (
EnvironmentVariableTarget.User). - Changes persist beyond the current process and are stored in the Windows registry.
- The variable becomes available to new processes started by the current user.
- Requires appropriate permissions to modify user-level environment variables.
Cross-platform environment
When running on cross-platform systems (Linux, macOS):
- Environment variables are set at the Process level (
EnvironmentVariableTarget.Process). - Changes are temporary and only affect the current process and its child processes.
- Variables are not persisted after the process terminates.
- No special permissions are required because changes are scoped to the current process.
Technical details
The activity uses an internal TargetFramework property to determine the execution context. This behavior is determined automatically by the UiPath runtime based on the project type and cannot be configured through the activity properties.
Best practices
- For Windows workflows, use this activity when variables must persist across process restarts or be available to other applications.
- For cross-platform workflows, plan for process-level scope and use alternative persistence (configuration files, databases) when needed.
- For portable workflows, design assuming process-level scope to ensure consistent behavior across platforms.
Validation
The activity validates that the Name parameter is not null or empty and that all required arguments are provided. Invalid operations throw an InvalidOperationException with a descriptive error message.
