ok so i am having this issue, but I cannot find any documentation on how to fix it.

my code works if the app is installed, but if a user without the app installed views my page, it does not... what am i missing here???

I am doing a very simple thing.   getting the owner id and viewer id and passing those variables to my flash application.  :

function init() {        

os = opensocial.Container.get();    

dataReqObj = os.newDataRequest();  

var ownerReq= os.newFetchPersonRequest(opensocial.DataRequest.PersonId.OWNER);    

var viewerReq = os.newFetchPersonRequest(opensocial.DataRequest.PersonId.VIEWER);    

dataReqObj.add(ownerReq);          

dataReqObj.add(viewerReq);          

dataReqObj.send(viewerResponse);

}

function viewerResponse(data) {    

var owner = data.get(opensocial.DataRequest.PersonId.OWNER).getData();    

var viewer = data.get(opensocial.DataRequest.PersonId.VIEWER).getData();    

ownerID = owner.getId();    

userID = viewer.getId();    

AC_FL_RunContent( 'codebase','download.macromedia.com/.../swflash.cab','width','280','height','280','title','mp3candy','src','www.freelance-photographer.us/.../mp3playermySpace2','quality','high','pluginspage','www.adobe.com/.../download.cgi','flashvars','fb_sig_profile=m'+ownerID+'&fb_sig_user=m'+userID+'&ms=y','wmode', 'transparent','movie','www.freelance-photographer.us/.../mp3playermySpace2' ); //end AC code

}    

the ac_fl_runcontent code was screwed by the blog comments, but the relevant code is the following:

'fb_sig_profile=m'+ownerID+'&fb_sig_user=m'+userID
