I'm not able to run AR with Unity, I followed all the steps in the guide but

I found the solution, the problem was a space in the directory name !

Thanks for the support

Be sure to re-upload your targets to the TMS for 1.5, and download the new dataset. Import it into Unity, and use the QCAR menu "Rename 1.0.x Data Set" option to convert it for use with 1.5. If you can't see the QCAR menu at the top try saving the project.

It sounds like you might be having trouble with 1.0 as well though? In that case, make sure none of your trackables have names with contentious characters (keep them alphanumeric).

If you're still having trouble please send the config file to

and we'll take a look. Also let us know what version of Unity you are using.

I just tried the 1.0 stable but I get the same error and no trackable images will shows up in the drop down list
