Installing, updating, and deleting Yandex Telemost using MSI

You can use MSI to install Yandex Telemost on computers running 64-bit Windows 10 or later versions. This method won't work for 32-bit Windows 10 and older versions, but you can use the browser version of Yandex Telemost.

Using the MSI file, system administrators can install the application for all employees in the company at once or for specific users only.

Install the application

Important: If there are multiple accounts on one computer with the Yandex Telemost application installed from an .exe file, you need to first uninstall it from each account.

If there's only one user account on the computer, you don't need to uninstall the Yandex Telemost application before starting installation using MSI.

Using MSI, you can install Yandex Telemost in the regular or silent mode.

1. Download the MSI installation file here.

2. Open the command line as an administrator.

3. Enter the command msiexec /i "path to file YandexTelemostSetup_9999.msi", and then add the required parameters, separating them with spaces:

   • /qn to start a silent installation without pop-ups.

   • ALLUSERS="1" MSIINSTALLPERUSER="" to install Yandex Telemost for all employees. If you're launching a silent installation, make sure to specify these parameters.

   • Add SKIP_LAUNCH=1 not to launch Yandex Telemost immediately after installation.

   • Add NODESKTOPSHORTCUT=1 not to create a desktop shortcut. If you don't enter this parameter, the shortcut will be created on all users' desktops.

     Command example

     msiexec /i "C:\Downloads\YandexTelemostSetup_9999.msi" /qn ALLUSERS="1" MSIINSTALLPERUSER="" SKIP_LAUNCH=1 — silent installation for all users without launching the application.

4. Click Enter.

The application will be installed to the folder C:\Program Files\Yandex\YandexTelemost.

Update the application

By default, when installing using an MSI file, Yandex Telemost updates automatically. If the auto-update didn't work for some reason, you can reinstall the application by following the instructions.

It's not recommended to update Yandex Telemost manually, as this will interrupt the current sessions for all users.

Uninstall the application

Open the command line, type msiexec /x "path to file YandexTelemostSetup_9999.msi" and press Enter.

Command example

msiexec /x "C:\YandexTelemostSetup_9999.msi"
