A virtualized application on an App-V client fails to launch with the following error:
The Application Virtualization Client could not launch application name.
No connection could be made because the target machine actively refused it.
Error code: xxxxxxx-xxxxxx2A-0000274D

Cause

This issue can occur if the HREF attribute in the application .osd file is configured to use the RTSPS protocol but the App-V Management Server is configured to use the RTSP protocol.

Resolution

To resolve this issue, perform the following steps:
1. On the App-V Management Server, open the application .osd file and scroll down to the following line:

<CODEBASE HREF="rtsps://servername:322/ApplicationDirectory/Application.sft"

2. Change the protocol from RTSPS to RTSP and the port number from 322 to 554 like the example below:

<CODEBASE HREF="rtsp://servername:554/ApplicationDirectory/Application.sft"

3. Save the application .osd file.
4. Open the Application Virtualization Client MMC snap-in on the App-V client and refresh the Publishing Server.
5. Launch the application on the App-V client.
