1. Access the machine where the Blackbaud Web Services are installed (generally, this is the server)
  2. Go to the Blackbaud install directory (usually C:\Program Files (x86)\Blackbaud)
  3. Open the Blackbaud Web Services folder
  4. Look for the Blackbaud.WebServices.Adapter.Common.DLL (or any other DLL file)
  5. Right click on the file and select Properties > Details
  6. The entry next to the product version is the version of Blackbaud Web Services
Alternatively, if you are hosted with Blackbaud Hosting Services, your Blackbaud Web Services will be on the most recent version and will match the version of the Luminate Online plug in found in The Raiser's Edge database. To find this, access the plug in and click Options > About.
