We have updated Cirque du Soleil today which should resolve the following issues:
- Application remains seen as "running" by Steam client.
- Minor bug fixes.

Please also read this FAQ in case you have trouble running the application:

Q: Can I launch the application on Rift?
A: No, this Steam release currently supports HTC-Vive only.

Q: Streaming option is disabled (grayed-out). Why?
A: The Streaming feature is currently being tested out and will be made available when ready.

Q: I bought an experience DLC, why am I being asked to download additional data?
A: For the best experience we currently download our video, audio and data from our own CDN. We may be looking at options to deliver DLC data inside Steam DLC downloads in the future. Make sure you have enough free disk space.

Q: When launching the app I see an option to launch using an alternate method, why?
A: Please use the default (first) method. If the application does not launch, please try to update the application via Steam to make sure you are at the latest and try again. Only as a last resort, you may use the "alternate method" option, which should run the application executable directly but may not quit correctly leaving a download process in the background.

Q: When I download an experience, I need to watch the download bar progress ?
A: No. The application uses a background downloader and you can either remove your headset or browse elsewhere while the content downloads. You can even close the application and come back to it later.
