Hi,

We are running Aspose.Slides for Reporting Services and running in to a issue we are hoping you can help us out with. When we are trying to generate report we are getting below error. We have licenses file located in C:\Program Files\Microsoft SQL Server\MSRS13.MSSQLSERVER\Reporting Services\ReportServer\bin\Aspose.Slides.ReportingServices.lic. Also in the PowerPoint export we see Warning:Object reference not set to an instance of an object.

@kenverma,

I have observed the issue shared by you and suggest you to please try using Aspose.Slides for Reporting Services 18.3 on your end first. The warning messages shared by does show the locations where Aspose.Slides is looking for license on your machine. You need to make the license file available with proper name (as suggested) along with assurance that the access to license file is available. I hope the shared information will be helpful.
