HTTP 4.4 Not Found error when Appeon Workspace tries to get auto-upgrade

If Appeon Workspace is configured to auto-upgrade, it will get automatically upgraded when a newer version is available in the server. However, when it tried to start the upgrade, an HTTP 404 Not Found error is displayed and the upgrade failed.

Solution: Add a script mapping for awshandler in the IIS server by executing the following commands:

Step 1: Log in to Windows with administrator rights.

Step 2: Change to the "system32/inetsrv" directory in the command window, and then execute the following command:

For 32-bit:

appcmd set config /section:handlers /+[name='awshandler',path='*/awshandler',verb='GET,HEAD,POST',modules='IsapiModule',scriptProcessor='C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll',preCondition='classicMode,runtimeVersionv2.0']

For 64-bit:

appcmd set config /section:handlers /+[name='awshandler',path='*/awshandler',verb='GET,HEAD,POST',modules='IsapiModule',scriptProcessor='C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll',preCondition='classicMode,runtimeVersionv2.0']

Add a script mapping (for 32-bit)
