When running a PowerServer application that is deployed to IIS Web server, the browser only pops up a "Failed to invoke remote procedure" error message.
Cause: The IIS server requires Scripts and Executables permissions on the applications.
Solution:
Step 1: Open the Internet Information Service in the Administrative Tools in the IIS Web server.
Step 2: Go to Default Web Site Properties > Home Directory, and change the Execute Permissions to "Scripts and Executables".
