Hi jpauclair.

This is the step i have taken to solve the problem. You can try it out.

1. Create a new project and import the unity package (cloudreco-3-0-10).

2. Delete the main camera.

3. Drag the "Vuforia-3-ColudRecognition" located at "scene" in the assets to the "hierarchy" tab.

4. Print out the "target_stones_A4.pdf" located at "testing\Assets\Editor\QCAR\ForPrint" on a A4 paper.

5. Run the play mode and scan the  "target_stones_A4" paper with your webcam. A teapot model with show on the paper in your screen.

6. Create another new project and import the vuforia package into your Unity.

7. Create your Vuforia project and run the Play Mode.

Hope this do helps you. 

What steps exactly solved the problem?

I realize that and getting PlayMode to work is the goal and the fix for Windows Unity. But right now, it appears that you are having a CloudReco connection error. As a troubleshooting step, running on a device and watching Logcat may provide more info than Unity's Console. You can check Unity's Console first for a more specific error or clue about your network. If none is found, compiling to the device and watching the logs might reveal more. It could also give us a clue if your device is able to connect, but your computer is not.

I am not even trying to build on mobile device for now, just trying to use the editor play mode.

Could you compile and run the Cloud Reco 3.0.10 sample app on your Android device and watch the logs in Logcat and see if there's any more specific connection errors being reported?

the scene "Vuforia-3-CloudRecognition" gives me a "Service unavailable, try again later" popup

I downloaded the cloud sample app, runned all the scene in play mode (in the editor)

The last scene doesn't connext "(connection unavailable"

I came back to my original projet, tried in the editor again. Same thing."No network available"

Is there any kind of non-cloud-based mode I can use? ... Like in other AR frameworks.

Other non-Cloud samples won't fix the issue. How far did you get in the steps? Are you receiving an error?

No need to create a new scene. Find and open the existing scene in the sample app and then start PlayMode and point it to the "stones" or "chips" targets we provide. A teapot should then appear once it is recognized through the cloud.

Hi ibancel...
How to make sure my device has approximatly correct time/date???

It's not working for me either. I've followed the instructions with the cloud reco sample but i had the same error. Then I deleted Unity 5 and reinstalled Unity 4.6.4 and it's still not working.

I saw in the other discussion that a moderator said

maybe the problem is due to summer time ?

The instruction written "Run Cloud Reco 3.0.10 sample app" does it means i drag the ArCamera into the hierarchy side and run the Play Mode?

After following the instructions involving CloudReco 3.0.10, did you run the ImageTargets 4.0.103 sample app (or other 4.0.103) sample successfully?

Hi, dm3d.

In the link you mention before, i create a new project and run with the "Cloud Reco Sample App Unity 3.0.10".

After that, i create another new project and run with the Vuforia.

Am I doing it right?? 

Currently, Vuforia doesn't support Unity 5. To avoid various errors and incompatibilities, I'd suggest using Unity 4.6.3f1.

And you might want to check out our samples for reference if you are creating a new project:

Hi dm3d. Thanks for your reply. I follow the instruction in the link. 

After i drag the 'teapot' into the hierarchy tab and click on the play button, it show an error ''All compiler errors have to be fixed before you can  enter the playmode!''.

Please follow the instructions in this post:
