As an administrator, you can install Slido for Windows (PowerPoint Add-in) using our MSI file and do a bulk install for users in your organization. With available command line parameters, you can turn off update notifications for the end users or execute a silent installation.

System requirements


You need to meet the following system requirements to install Slido for Windows using our MSI file:

  • Microsoft PowerPoint 2013 and later (32 or 64-bit)
  • Windows 10 2004 and later (64-bit)
  • .NET Framework 4.6.2
  • User Account Control is enabled

Slido for Windows requires at least .NET Framework 4.6.2, and it is fully supported to run on .NET Framework 4.8.

We support Microsoft Office for desktop in the Click-to-Run edition. The special editions installed in Windows Store or Microsoft Store mode are not supported - these two editions do not support add-ins extensibility. You can upgrade these editions to the Click-to-Run edition to add support for add-ins.

In general, we recommend Windows 10 2004 release and newer. Slido for Windows will also work on Windows 1809 LTSC and Windows 1909 Enterprise editions.

Install Slido for Windows


For bulk installations, you can use the MSI file with a third-party distribution software to bulk install Slido for Windows to selected users or computers.


Administrator permissions are required, as this is a per machine installation.


You can add the following command line parameter to disable update checks and prevent users from updating the Add-in to have full control over the update process.






0 = product will check for updates (default)


1 = update checks are disabled

Do not show notifications for the users to update to the new version of the Slido Add-in.


Example: msiexec /i C:\SlidoAdmin_x64_v0.19.0.msi DISABLE_UPDATE_CHECKS=1

Where “C:\SlidoAdmin_x64_v0.19.0.msi” is the path to the MSI file downloaded to the computer.


Silent installation

We support silent installation and all the other standard Windows Installer parameters (msiexec.exe) from the command line.

Example: msiexec /i C:\SlidoAdmin_x64_v0.19.0.msi /quiet


Installing updates

We regularly release updates to Slido for Windows but the major updates happen once in a quarter. To install the latest version of the Add-in, you can always find it on the link shared in the download section.


To find out what the latest version number is, you can visit and compare it by checking the original MSI download file stored on your computer.




Slido for Windows can be configured using Group Policy Objects. You can import our administrative template files into your Central Store and set Slido for Windows configuration directly from Group Policy Objects console.

Troubleshooting Slido for PowerPoint



  • Slido button is not available in the PowerPoint
  • Sidebar is not loading and/or it shows an error

This may be caused by the policy set in Windows Defender which prevents add-in to be loaded by PowerPoint or by blocking child processes to be created by Microsoft Office applications. If you use management software to block this kind of behavior in Microsoft Office applications, please reconfigure it to enable Slido add-in to work properly.

Slido for PowerPoint requires the process CefSharp.BrowserSubprocess.exe to be run as a child process of Microsoft PowerPoint.


If you’re using Microsoft Endpoint Manager (former Microsoft Intune) to manage the devices, you may have to configure the Attack Surface Reduction policy to enable Slido for PowerPoint.

You can adjust the Endpoint Security Policy to exclude Slido for Windows installation path from Attack Surface Reduction rules. Here are the steps:

  1. Open Microsoft Endpoint Manager console
  2. Got to Endpoint security
  3. In the Manage section, open Attack surface reduction
  4. Select existing policy which has the Block all Office applications from creating child processes setting enabled
  5. Go through the wizard and configure the policy rule Exclude files and paths from attack surface reduction rules.
  6. Enter the path %ProgramFiles(x86)%\Slido\Slido for Windows to exclude Slido add-in and CefSharp browser processes from this rule
  7. Save the policy
