Error 404 - File or directory not found

You may encounter a 404 - File or directory not found error, when you start to run an application.

Cause: The Appeon folder is not in the application-related IIS home directory (For example: your PowerServer Web Component might be installed in C:\Program Files (x86)\Appeon\WebComponent2017R3 by default, if you did not change the path when installing it).

Solution: Copy the Appeon folder to the application-related IIS home directory (for example: C:\inetpub\wwwroot) to solve this issue.
