Installing in silent mode

The Syncfusion® Essential® Studio JavaScript – EJ2 installer supports installation and uninstallation via the command line in silent mode.

Command line installation

To install through the command line in silent mode:

  1. Run the Syncfusion® JavaScript – EJ2 installer by double-clicking it. The Installer Wizard opens and extracts the package.
  2. The syncfusionejs2_<version>.exe file is extracted into the Windows Temp directory.
  3. Open the Temp folder by running %temp% in the Run dialog (Win + R). The syncfusionejs2_<version>.exe file is located in one of the subfolders.
  4. Copy the extracted syncfusionejs2_<version>.exe file to a local drive.
  5. Exit the Installer Wizard.

  6. Run Command Prompt as an administrator, then run the installer with the following arguments.

    Syntax

     "installer file path\SyncfusionEssentialStudio<product>_<version>.exe" /Install silent /UNLOCKKEY:"<product unlock key>" [/log "<log file path>"] [/InstallPath:<install location>] [/InstallSamples:true|false] [/InstallAssemblies:true|false] [/UninstallExistAssemblies:true|false] [/InstallToolbox:true|false]

    Arguments inside square brackets are optional.

    Example

     "D:\Temp\syncfusionejs2_20.2.0.36.exe" /Install silent /UNLOCKKEY:"your-unlock-key" /log "C:\Temp\EssentialStudioPlatform.log" /InstallPath:"C:\Syncfusion\20.2.0.36" /InstallSamples:true /InstallAssemblies:true /UninstallExistAssemblies:true /InstallToolbox:true

    Replace 20.2.0.36 with the Essential® Studio version, and replace your-unlock-key with the unlock key for that version.

  7. Essential® Studio for JavaScript (Essential® JS 2) is installed.

    To confirm the install, check the Syncfusion® Control Panel entry, or run the following PowerShell command to verify the installed version:

     Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* |
   Where-Object { $_.DisplayName -like 'Syncfusion*JavaScript*' } |
   Select-Object DisplayName, DisplayVersion

    A successful silent install returns exit code 0. Other exit codes indicate an error; see the log file specified by /log for details.

Troubleshooting

Issue Possible Cause Suggested Fix
Installer fails with “Another installation is in progress.” Another MSI installation is currently running. End the running msiexec.exe process in Task Manager, or wait for the other install to finish. See Common Installation Errors.
“Controlled folder access seems to be enabled” alert. Windows Controlled folder access is blocking the install/samples location. Allow access for the installer in Windows Security → Virus & threat protection → Manage ransomware protection, or install to a non-protected folder.
Login to Install fails with an invalid credentials error. Wrong account, or the account does not own a license. Verify the account owns a Syncfusion® license, or use the Use Unlock Key option instead.
Silent install reports a non-zero exit code. Invalid arguments, missing unlock key, or path issues. Re-run with /log "<log file path>" and inspect the log for the exact error.
The “I agree to the License Terms and Privacy Policy” check box is disabled. The license text has not been scrolled to the end. Scroll the license text to the bottom before checking the box.
