This error "an error occured while trying to enable vuforia play mode" shows up in the web cam behaviour component of the arcamera gameobject. It is along side a "No webcam profile has been found for your webcam model" warning. If I use an external webcam the no webcam profile warning goes away and I am left with the error.
windows 10 64 bit
unity 5.3.4 32 bit
Seems like the problem typically occurs when using unity 64 bit on windows but I am positive I am running the 32 bit editor. Coworkers in a similar environment do not seem to have this problem. Thank you for your time and any help you may provide.
