Setup: License key is invalid error message


You keep getting the License key is invalid error even after copying both the license key file and serial number, and you reset IIS as a workaround, after which WorkflowGen works properly.


You have to remove the server cache. To do this:

  1. Stop IIS.

  2. Delete all files in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files.

  3. Restart IIS.
