Team,
Hi,
Thanks for your interest in Aspose.Slides.
I have tried to understand the requirement shared by you but unfortunately have not been able to understand that whether you are using Aspose.Slides for Reporting Services or Aspose.Slides for SharePoint. If you are looking for re-installing Aspose.Slides for Reporting Services then please visit this documentation link for your kind reference. This will help you achieve the goal for re-installing Aspose.Slides for Reporting Services. If you want to remove Aspose.Slides for Reporting Services as well then you can observe the files modified and can remove the added content as shared in above link to remove Aspose.Slides for Reporting Services.
For Aspose.Slides for SharePoint uninstall, please visit this documentation link. Please share, if I may help you further in this regard.
Many Thanks,
