Pre-Installation Requirement: Stop the SAS Web Parts Service

If you previously installed a release of SAS Web Parts for Microsoft SharePoint and you plan to upgrade to the latest release, you must stop the SASWebPartsService in Internet Information Services (IIS) Manager before you upgrade to the new release. For example, if you are running SAS Web Parts 6.1 for Microsoft SharePoint and you want to upgrade to the 6.11 release, you must first stop the SASWebPartsService 6.1 in the IIS Manager.
To stop the service website in IIS:
  1. Start the IIS Manager.
  2. In the Connections pane, expand the Sites folder for the server where the SAS Web Parts are installed and select SASWebPartsService61.
  3. In the Actions pane, expand the Manage Web Site section, and then click Stop.
