I am sorry to hear that you are having difficulties installing JuiceboxBuilder-Lite.
Under normal circumstances, all that should be necessary to install JuiceboxBuilder-Lite is to ensure that you have Adobe AIR installed and then double-click the 'JuiceboxBuilder-Lite.air' file.
If you were able to extract the Juicebox-Lite zip package successfully without any error messages, then it is unlikely that the 'JuiceboxBuilder-Lite.air' installation file is actually damaged or corrupt.
However, if you would like to check the integrity of your 'JuiceboxBuilder-Lite.air' (v1.4.3.2) file, then it should have the following properties:
Filesize: 1,376,245 bytes
MD5 hash: 1015798482f200693a23edb0d3c80bbd
SHA1 hash: b980edd071f086071dc860fdbce4ac687d8660b0
You can check the MD5 and SHA1 hashes of files with a free program such as HashCalc.
Please try the following. Make sure that you using an Administrator User Account and then:
Uninstall Adobe AIR.
Make sure that no remnants of any failed JuiceboxBuilder-Lite install are still present on your system by searching your hard drive for the term 'JuiceboxBuilder' and manually deleting everything found.
Download the latest version of Adobe AIR from here: http://get.adobe.com/air/
Install Adobe AIR by right-clicking the 'AdobeAIRInstaller.exe' file and selecting 'Run as administrator'.
Now try reinstalling only JuiceboxBuilder-Lite, allowing the application to install to the default location.
If you continue to experience problems, then there is a fairly comprehensive list of things to check/try (such as temporarily deactivating your anti-virus program in case this is somehow interfering with the JuiceboxBuilder-Lite installation process) in this forum thread.
Hopefully one of the suggestions above (or in the forum thread) will help.
