So there is an obvious clash between Safari and the Jukebox Forum.
No-one else has reported any issues with the forum when using Safari. Do you maybe have any browser extensions installed which might be interfering with things? If you do have any browser extensions installed, then try temporarily disabling them to see if this makes a difference. Don't worry about creating a couple of test posts. I can delete them later.
If anyone reading this thread uses Safari and has experienced any issues with the forum, please let me know in this thread (post using a different browser if necessary). Thank you.
Juicebox quits before starting
For anyone else reading this thread, here are the suggestions I have already made to the original poster via email:
(1) Try uninstalling and then reinstalling JuiceboxBuilder-Pro but, before reinstalling the application, please delete the following files and folders manually to make sure that there is nothing left behind from previous installations.
(2) If you have any security software installed, the try temporarily disabling it (whilst both installing and running JuiceboxBuilder-Pro) to make sure that it is not somehow interfering with the application.
I would not normally recommend disabling security software but disabling it temporarily may be a useful step in troubleshooting your problem. Please do so at your own risk and disconnect from the internet before doing so.
I'm sorry to hear that neither of these suggestions has helped.
It sounds like you might have an underlying problem with Adobe AIR on your system.
To try to narrow down possible causes, try installing and running a different Adobe AIR application to see if the same problem occurs.
You can download some sample AIR applications from here: https://www.adobe.com/devnet/air/sample … cript.html
If you find that the problem happens with all AIR applications, then the problem is with Adobe AIR itself (rather than with JuiceboxBuilder-Pro). If this is the case then it might be helpful to post in the Adobe AIR forum: https://forums.adobe.com/community/air
I realise that this will not directly solve your problem but it might help to point you in the right direction.
Please let me know how you get on.
Incidentally, I have found these two unanswered queries in the Adobe AIR forum which seem to accurately describe the problem that you are experiencing. (It is unlikely that either of the posters were using JuiceboxBuilder-Pro so I expect that the problem is an Adobe AIR issue of some kind.)
Maybe posting in the Adobe AIR forum is, indeed, the best course of action.
Try creating a new user account on your computer and then try installing JuiceboxBuilder-Pro under the new user account to see if this works. Maybe there's something strange going on with your current user account.
I hope my notes above help to some degree.
