Hi Steven,
I can't uninstall Adobe AIR runtime - version 51.0.1.3
I finally sorted the problem with some help from AIR GitHub https://github.com/airsdk/Adobe-Runtime … sions/3408
I updated to the latest version of Adobe AIR and then ran the Adobe AIR installer that was in the 'Applications' folder and not the uninstaller that was in the 'Utilities' folder and uninstalled Adobe AIR. That allowed me to then install the AIR runtime including WebKit - version 33.1.1.744.
It also says Upgrade to Juicebox-Pro in the top right corner but I have paid for and downloaded the Juicebox-Pro installer.
I have sorted that problem. I uninstalled JuiceboxBuilder Pro. Then changed the name of the 'JuiceboxBuilder-Pro' folder in the 'Documents' folder to 'OldJuiceboxBuilder-Pro'. Reinstalled JuiceboxBuilder Pro by running the JuiceboxBuilder-Pro.air installer. It created a new 'JuiceboxBuilder-Pro' folder in the 'Documents' folder and I then copied my presets from the 'OldJuiceboxBuilder-Pro' folder into the new 'JuiceboxBuilder-Pro' folder.
I suspect it was a permissions problem. All working fine now. Thank you.
