If you have been able to extract the Juicebox-Pro zip package without any errors, then it is unlikely that the 'JuiceboxBuilder-Pro.air' installation file is damaged or corrupt.

Ordinarily, none of the suggestions below should be necessary but, as you are experiencing difficulties, the list contains a fairly comprehensive list of things to check/try.

(1) Make sure that you are logged in with a User Account which has administrative rights. If necessary, create a new Administrator User Account and install Adobe AIR and JuiceboxBuilder-Pro from within this new account. (Windows).

(2) Make sure that you are using the latest version of Adobe AIR (v13.0) which can be downloaded from here.

(3) Install Adobe AIR not just by double-clicking the 'AdobeAirInstaller.exe' installation file but by right-clicking it and selecting 'Run as administrator...'. (Windows)

(4) Uninstall any existing version of JuiceboxBuilder-Pro:
Mac: Delete the 'JuiceboxBuilder-Pro' file from the Applications folder and empty your Trash.
Windows: Use the uninstaller in the 'Control Panel -> Programs -> Uninstall a program...' list.

(5) Make sure that no files are left behind from any existing version (or failed install) by manually deleting the following folders from your hard drive:
Mac: /Users/your_username/Library/Application Support/Adobe/AIR/ELS/JuiceboxBuilder-Pro
Windows: C:\Program Files (x86)\JuiceboxBuilder-Pro
Windows: C:\Users\your_username\AppData\Roaming\Adobe\AIR\ELS\JuiceboxBuilder-Pro
Windows: C:\Users\your_username\AppData\Roaming\JuiceboxBuilder-Pro
Windows: C:\Users\your_username\My Documents\JuiceboxBuilder-Pro
You may need to Show hidden files to find some of the above locations in Windows Explorer.

(6) Search your hard drive for the term 'JuiceboxBuilder-Pro' and delete any and all entries found (to be absolutely sure that nothing remains from a previous or failed install).

(7) Ensure that the 'JuiceboxBuilder-Pro.air' installation file is on your Desktop or in a non-restricted folder on your hard drive (and not on an external or network drive).

(8) Disconnect/unmount all drives other than the main hard drive (including time machine backups). (Mac)

(9) Ensure that any security software that you may have installed is not interfering with the installation process.

(10) Install JuiceboxBuilder-Pro following the 'Installation' instructions in the JuiceboxBuilder-Pro User Guide.

Hopefully the tips above will allow you to successfully install JuiceboxBuilder-Pro.
