Error
When attempting to install ExtendInsights from Microsoft Marketplace, you may encounter the following error:
Message: "Internal Server Error" ErrorMessage: "Unable to read RPS data encryption certificate"
Why This Happens
This error is generated by Microsoft’s AppSource or Office Add-in installation service while processing the marketplace request.
It does not indicate an issue with ExtendInsights or your CloudExtend configuration.
The error typically occurs when Microsoft’s backend service is unable to load or validate an internal encryption certificate required to process the installation. As a result, the Microsoft Marketplace page cannot complete the add-in installation request.
Because the issue occurs within Microsoft’s marketplace infrastructure, retrying the same direct Marketplace link may continue to produce the error.
Resolution
You can bypass the Microsoft Marketplace webpage by installing ExtendInsights using one of the following methods.
Option 1: Install ExtendInsights Directly from Excel
Open Microsoft Excel.
Go to Home or Insert, depending on your Excel version.
Select Add-ins or Get Add-ins.
Search for ExtendInsights.
Select the app, then click Add.
Installing the app from within Excel uses the Office Add-ins interface instead of the direct Microsoft Marketplace webpage.
Option 2: Ask Your Microsoft 365 Administrator to Deploy the App
Your Microsoft 365 administrator can centrally deploy ExtendInsights to users or groups through the Microsoft 365 Admin Center.
This is the recommended option when:
Multiple users need access to ExtendInsights
Users are not permitted to install Office add-ins
Your organisation manages add-ins centrally
The app cannot be installed directly from Excel
After the administrator completes the deployment, ExtendInsights should become available in Excel for the assigned users.
