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_v1.0.0.msi DISABLE_UPDATE_CHECKS=1
Where “C:\SlidoAdmin_x64_v1.0.0.msi” is the path to the MSI file downloaded to the computer.
We support silent installation and all the other standard Windows Installer parameters (msiexec.exe) from the command line.
Example: msiexec /i C:\SlidoAdmin_x64_v1.0.0.msi /quiet
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 slido.com/powerpoint 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.

The sli.do addin for PowerPoint does not seem to like a proxy server with authentication.
13:55:51.775 INF] The addin is connected to Slido API through a proxy. (Proxy server address: "http://xxxxxxx:8012/"). real servername replace by xxxxx
[13:55:52.519 ERR] Unable to create a new app instance on server. Missing proxy authentication (required scheme "BASIC realm="PROXY_INTERNET"").
System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required.
at System.Net.HttpWebRequest.EndGetRequestStream(IAsyncResult asyncResult, TransportContext& context)
at System.Net.Http.HttpClientHandler.GetRequestStreamCallback(IAsyncResult ar)
So it detects very well the correct proxyserver, but there is no prompt for a login/pwd for the proxyserver, as most programs do in such case.
Slido for Windows does not support proxy with authentication.
One option is to configure proxy to not require authentication for these domains:

Troubleshooting Slido for PowerPoint
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:
%ProgramFiles(x86)%\Slido\Slido for Windowsto exclude Slido add-in and CefSharp browser processes from this rule
My PPT had slido addin but when I was login to my account it wasnt let me add any poll , it still said login. I uninstalled and now its not letting me install
It sounds as if your Slido add-in may be blocked by your organizations group policy settings. Your IT administrator should be able to assist with this.
Let me know if this works!
