• Review the SSRS Evaluation license used in your environment. If it has expired, follow these steps:

  1. Follow Control Panel > Uninstall a program > Microsoft SQL Server Reporting Services > Uninstall/Change.
  2. Once the SSRS window opens, select Upgrade Edition > enter the product key to license your SSRS instance.

Troubleshooting the expired evaluation license

To establish whether your SSRS instance has an evaluation license, open Start > Microsoft SQL Server Reporting Services folder > Report Server Configuration Manager. Once you've connected to the server, check the Edition line in the server window.

If your SSRS instance edition is Evaluation, check the install date for the SSRS via Start > Settings > Apps & features or Control Panel > Uninstall a program. If the period since the installation date exceeds 6 months, your SSRS Evaluation license has expired.

Review the SSRS logs in C:\Program Files\Microsoft SQL Server Reporting Services\SSRS\LogFiles::

The report server has encountered a configuration error.
Microsoft.ReportingServices.Diagnostics.EvaluationCopyExpiredException:
The evaluation period for this instance of Microsoft SQL Server Reporting Services has expired.
A license is now required.
