App Formats for Windows

Installer Format Description
EXE

For regular users.
Download: eXpress | eXpress Corporate

  • Installs into the user profile folder. An
    ETS
    app can be installed in Program Files. In this case, administrator rights are required for installation, updating, and removal.
  • Does not support running with SYSTEM privileges, so it is not suitable for SCCM.
  • Supports automatic updates. For an
    ETS
    app, a custom update server must be configured.
SHA512 hashes and version information for the eXpress desktop app can be checked in YML files: eXpress | eXpress Corporate.
MSI

For corporate deployment.
Download: eXpress | eXpress Corporate

  • Installs to Program Files — installation, update, and uninstallation will require administrator privileges.
  • Compatible with SCCM and Kaspersky Security Center.
  • Does not update automatically.

Auto-Launching the App on Windows Startup

Auto-Launch After Installation

Installer Format Description
EXE CMD: "eXpress Setup.exe" "--force-run"
MSI CMD: msiexec /i "eXpress.msi" AUTO_START=1
⚠️ Use AUTO_START=0 for SCCM or Kaspersky Security Center to prevent the app from running with SYSTEM rights! Otherwise, file drag-and-drop from Explorer won’t work.

Call Blocking (VDI Mode)

Installer Format Description
EXE Create an AppConfig.ini file in the application folder and add:
[AppConfig]
Vdi="true"
MSI CMD: msiexec /i "eXpress.msi" VDI="true"
Requires version 3.64 or higher. This setting disables calls in the application — it is needed where calls are not supported or are prohibited, for example in some VDI environments. Default value is false.

Installing Certificates on Windows

CTS
ETS

By default, you do not need to install corporate server certificates. If the connection doesn't work without them, install them:

  1. Open the certificate file and click Install Certificate.
  2. Select the store location:
    • Current User — the certificate will work for you. Administrator rights are not required.
    • Local Machine — the certificate will work for all users of this computer. Administrator rights are required.
  3. Select Place all certificates in the following store > Browse.
  4. Enable Show physical stores.
  5. Select the store:
    • rootCA > Trusted Root Certification Authorities
    • interCA > Intermediate Certification Authorities
  6. Confirm and complete the installation. The system will show a warning about installing a root certificate — accept it.
  7. The app keeps running in the notification area. Exit it completely and launch it again.

If your organization's server has switched to Ministry of Digital Development National Certification Authority certificates, see the instructions.

Credential Storage on Windows

Authentication data is stored in Windows Credential Manager under *desktop/auth.* entries.

For Administrators: Managing Keys Storage
The app creates dozens of keys in Credential Manager because Windows limits the length of a single entry.

Deleting Keys

If you delete authentication keys from Credential Manager, the authentication screen will appear after restarting the app. Keys are preserved during standard app uninstallation.

Application-Specific Keystore

ETS
Since version 3.42, you can configure a non-system keystore in the %AppData%\app_name folder in an
ETS
app build. Contact eXpress support to get more details.

Updating on Windows

An app installed via EXE finds updates on its own and offers to install them (details). Check for updates manually: Settings (avatar button) > Check for updates.

If the app is installed by using the MSI package, install the new version manually.

For Administrators: Additional Update Options
Order and combinations of keys and parameters in the CMD:
"*.exe"/"*.msi" /key parameter1 parameter2
For an
ETS
app, replace eXpress with it's name.

Disabling Update Checks

  • Create an AppConfig.ini file in the installation folder and add:
    [AppConfig] AutoUpdate="false" Update="false"
    Pre-made file: AppConfig.ini
  • Use the MSI installer: updates are disabled in it, and the INI file is created automatically.
  • Use Software Restriction Policies in Windows to block EXE update installers from running in the %LOCALAPPDATA%\express-updater folder.
  • Block access to the updates.express.ms resource. If an
    ETS
    app has its own update server configured, the app uses it.

Closing the App Before Updating

⚠️ Close the app before updating. Otherwise, additional dialog boxes may appear, or you may need to restart the computer.

Installer Format Description
EXE
  • Manually via the system tray: right-click the icon > Exit
  • Via Task Manager: (Ctrl+Shift+Esc) > right-click processes > End Task
  • Using CMD: taskkill /IM eXpress.exe /F
MSI
  • CMD: msiexec /i "eXpress.msi" CLOSE_APP=1
    ⚠️ Use CLOSE_APP=1 to avoid a reboot. After a reboot, launching from a shortcut does not work; a fix is pending. If you're an administrator, notify users not to reopen the app until the update is complete.
  • SCCM: properties of the application being installed > Deployment Types tab > Edit > Programs tab > in the Installation program field, add the CLOSE_APP=1 switch, for example: msiexec /i "eXpress.msi" /qn CLOSE_APP=1. To make SCCM warn the user that the app must be closed, on the Installation behavior tab, click Add and specify Executable file name = eXpress.exe, Display name = eXpress. Then, during required deployments, SCCM will close the app automatically. For an ETS application, use its name instead of eXpress.

MSI CMD: msiexec /i "eXpress.msi" /qn CLOSE_APP=1

Update Without PC Rebooting

Required if updating via MSI while the app is running. The previous version will continue working until reboot.

⚠️ After a reboot, the app does not launch; you will need to repair the installation. Known issue, fix in progress.

Installer Format Description
EXE -
MSI CMD: msiexec /i "eXpress.msi" /norestart

Auto-Launch After Update

Installer Format Description
EXE CMD: "eXpress Setup.exe" "--force-run"
MSI CMD: msiexec /i "eXpress.msi" AUTO_START=1
⚠️ Use AUTO_START=0 for SCCM or Kaspersky Security Center to prevent the app from running with SYSTEM rights. Otherwise, file drag-and-drop from Explorer won’t work.

Uninstallation on Windows

Manually: Settings > Apps > Apps & Features or Programs and Features in Control Panel.
For Administrators: Additional Uninstallation Options
Order and combinations of keys and parameters in the CMD:
"Uninstall *.exe"/"*.msi" /key parameter1 parameter2
For an
ETS
app, replace eXpress with it's name.

Closing the App Before Uninstallation

⚠️ Close the app before uninstalling it. Otherwise, additional dialog boxes may appear or you may need to restart the computer.

Installer Format Description
EXE
  • Manually via the system tray: right-click the icon > Exit
  • Via Task Manager: (Ctrl+Shift+Esc) > right-click processes > End Task
  • Using CMD: taskkill /IM eXpress.exe /F
MSI
⚠️ In versions up to 3.72, the CLOSE_APP=1 switch only works during installation and update. Therefore, before uninstalling:
  1. Manually terminate the application, for example taskkill /IM eXpress.exe /F;
  2. Add the /norestart switch to the uninstall command.

If you don't do this, the removal will complete with code 3010. Some files will be deleted only after the computer restarts. In quiet mode, msiexec will restart the computer on its own and without warning.

Starting from version 3.72, the CLOSE_APP=1 switch also works during uninstallation.

Standard Uninstallation

Parameters and keys:

Installer Format Description
EXE
  • CMD: "%LOCALAPPDATA%\Programs\eXpress\Uninstall eXpress.exe"
  • If an
    ETS
    app is installed in Program Files: "%PROGRAMFILES%\app_name\Uninstall app_name.exe" /allusers
MSI ⚠️ Not recommended if the app is running.

Uninstallation with Progress Indicator (Unattended)

Installer Format Description
EXE -
MSI CMD: msiexec /x "eXpress.msi" /passive /norestart CLOSE_APP=1
⚠️ In versions up to 3.72, the application must be closed in advance — CLOSE_APP=1 does not work during uninstallation.

Silent Uninstallation

Installer Format Description
EXE CMD: "%LOCALAPPDATA%\Programs\eXpress\Uninstall eXpress.exe" /S
⚠️ The app will close if running.
MSI
  • CMD: msiexec /x "eXpress.msi" /qn /norestart CLOSE_APP=1
  • CMD: msiexec /x {product_code} /qn /norestart CLOSE_APP=1
    How to find the product code
⚠️ In versions up to 3.72, do not omit /norestart: in silent mode, msiexec restarts the computer without warning if the application was running at the time of uninstallation. Before silent uninstallation, terminate the application manually: the CLOSE_APP=1 switch does not work in this scenario. Starting from 3.72, you can use msiexec /x {product_code} /qn CLOSE_APP=1.

Uninstallation Without PC Rebooting

Required if uninstalling via MSI while the app is running. The previous version will continue working until reboot.

Installer Format Description
EXE -
MSI The remaining application files will be deleted the next time the computer restarts.
For Administrators: Complete App Removal on Windows

Perform this as recommended by support: for example, to delete credential keys saved on the computer.

For an
ETS
app, replace eXpress with it's name. To get the batch file to automate these steps on client machines, contact eXpress support.
  1. Close the app and uninstall it (see parameters and keys above).
  2. Delete folders:
    • Executable folder: %LOCALAPPDATA%\Programs\eXpress for EXE install; %PROGRAMFILES%\eXpress for MSI install or EXE install to Program Files
    • Cache folder: %APPDATA%\eXpress
      When uninstalling via the EXE uninstaller, the %APPDATA%\eXpress folder is removed automatically. If the app was installed using MSI, delete the folder manually.
    • Downloaded updates: %LOCALAPPDATA%\express-updater
    To navigate quickly: copy the path > Win+R > paste the path > Enter. If the folder doesn’t exist, an error will appear.
  3. Start menu > search for credential manager > Credential Manager > Windows Credentials > delete all *desktop/auth.* entries.
    You can use a PowerShell script. It requires administrator rights:
    1. Start menu > search for cmd > right-click Command Prompt > Run as administrator.
    2. In Command Prompt, run: powershell Set-ExecutionPolicy RemoteSigned This allows PowerShell script execution.
    3. Download PowerShell script > right-click it in Explorer > Run with PowerShell.
    4. Return to Command Prompt and run: powershell Set-ExecutionPolicy Restricted This restores the default PowerShell execution policy.
  4. If necessary, delete the shortcuts eXpress.lnk in the folders:
    • %APPDATA%\Microsoft\Windows\Start Menu\Programs (%ProgramData%\Microsoft\Windows\Start Menu\Programs)
    • %HOMEPATH%\Desktop (%PUBLIC%\Desktop)
    • %APPDATA%\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar
