Is my PowerPoint application up-to-date?
Slido requests that you update your Microsoft PowerPoint application regularly. For the best Slido experience, you should use Microsoft PowerPoint with the latest security and quality updates installed. We will notify you if we detect that the PowerPoint application is old and some Slido feature might not work correctly.
If we detect you are using PowerPoint without proper updates applied, we will display a notification message informing you to update your PowerPoint.
We require PowerPoint to meet or exceed these requirements:
- Office 365 Current Channel: Version 2209 (Build 15629.20208)
- Office 2021 Retail: Version 2209 (Build 15629.20208)
- Office 2019 Retail: Version 2209 (Build 15629.20208)

For more information, please reference the Release notes for Microsoft Office security updates.
We strive to bring you the best experience possible, so we strongly recommend installing the latest Microsoft Windows and Microsoft Office updates.
Please refer to the Microsoft guide for installing Office updates.

Add-in stays inactive. How do I activate it?
- Click Search in Windows

- Move the slider to the second position from top.
- Click OK
- Restart the computer (recommended)
💡 If this control isn’t available or it jumps back to the default position after restart, please contact your IT or system administrator.
Polls, Quiz or Q&A do not work in the Present mode. The slide stays white.
One of the reasons why this may be happening could be your network setting. Click “Show content”, copy-paste the text and send it to your IT Department to add an exception for Slido.
Text to send to your IT admin:
Slido for Windows currently doesn’t support proxy authentication of any kind. The processes -- Powerpnt.exe, Slido.exe and CefSharp.BrowserSubprocess.exe need to be able to run and connect to the following domains in order for the Slido add-in in PowerPoint to function properly:
*.slido.com
*.sli.do
*.sentry.io
log-api.newrelic.com
log-api.eu.newrelic.com
If you’re using some type of firewall or proxy server, you must make the above mentioned domains to be accessed by the Add-in processes. The rules or exceptions would need to be configured using the domain masks instead of entering specific IP addresses as we use dynamic IP addresses.
Sidebar isn’t loading and stays white (or shows an error)
One of the reasons why this may be happening could be your computer policy set by your system administrator. Click “Show content”, copy-paste the following text and send it to your IT admin to adjust the rules.
Text to send to your IT admin:
If you’re using Microsoft Intune to manage the devices, the Attack surface reduction policy is enabled which blocks any Microsoft Office applications from creating processes. Also, Windows Defender may be blocking some parts of the Slido Add-in, too.
You can adjust the Endpoint Security Policy to exclude Slido for PowerPoint installation path from ASR rules. Here are the steps:
-
Open Microsoft Intune and go to Endpoint security
-
In the Manage section, open Attack surface reduction
-
Click Create Policy
-
Use Platform: Windows 10 and Profile: Attack Surface Reduction rules
-
Click Create
-
Go through the wizard and configure the policy. Enter the path
%ProgramFiles(x86)%\Slido\Slido for Windowsin the Exclude files and paths from attack surface reduction rules policy. -
Save the policy and propagate it to your Windows devices.
Note: If you are using the Basic installer, you must exclude the path C:\Users\*\AppData\Local\Slido\Slido for Windows in the above mentioned policy.
If you need help or have questions, contact [email protected].
Sidebar is blurred
If your Slido sidebar is blurred, it’s most likely because you’re using multiple monitors and there’s a large difference in their resolution scale settings. If Slido detects a difference >100% between your monitors, you’ll see the below message as a banner in PowerPoint:
“Screens you use have different DPI scaling and the sidebar can look blurred depending on which screen PowerPoint is located.”
For example, sidebar blurriness may occur on a 4K monitor screen scaled to 200% or higher when it’s connected to a HD laptop screen scaled to 100%
Next steps:
The quickest fix is to move PowerPoint to your other monitor where the sidebar is not blurry. Otherwise you can follow the below steps to adjust your monitor scaling:
- Open your Start menu
- Begin typing Display Settings and launch the application
- Under Scale & Layout, check the Scale value for both monitors
- Change the settings so that the difference in scale is less than 100%
- Restart PowerPoint

These changes are needed to maintain the greatest privacy and security for our users, as well as enable us to build future products. To continue using Slido for Windows, we strongly recommend updating your operating system to Windows 10 or above

Slido add-in is blocked by Group Policies
The Group Policy settings may cause Slido add-in not being enabled in PowerPoint.
| Symptoms: • Slido add-in is not enabled in the Add-Ins section of the PowerPoint Options dialog box. • If you then open the COM Add-ins dialog box by clicking Go… button, you cannot enable any of the listed add-ins • Selecting any add-in from the list prompts the following text in the COM Add-ins dialog box: “The add-in you have selected is disabled by your system administrator.” |
Fixing the problem:
Through Group Policy, an administrator can manage the add-ins that are loaded in Microsoft Office programs. Contact your IT administrator to enable the Slido add-in in Group Policy.
The following Group Policy settings are used to manage this functionality:
- The list of managed add-ins
- Block all unmanaged add-ins
- Disable all application add-ins
- Disable Trust Bar Notification for unsigned application add-ins and block them
- Require that application add-ins are signed by Trusted Publisher
