I'm sorry to hear that you are having trouble installing JuiceboxBuilder-Pro.
I hope that my notes below help to resolve your problem.
First of all, please let me reassure you that JuiceboxBuilder-Pro v1.5.1 is fully compatible with Windows 10 and Adobe AIR 33.
I'm currently using the latest stable builds of both Windows 10 (19042.906) and Adobe AIR (22.214.171.1244) myself and run JuiceboxBuilder-Pro v1.5.1 without any problems.
If you are able to extract the 'juicebox_pro_1.5.1.zip' file without any errors, then it is unlikely that your 'JuiceboxBuilder-Pro.air' installation file is actually damaged.
However, if you would like to ensure that your JuiceboxBuilder-Pro installation file is not corrupt, then you can check that it has the following properties:
Name: JuiceboxBuilder-Pro.air (v1.5.1)
Filesize: 1,390,776 bytes
You can check the MD5 and SHA1 hashes of files with a free program such as HashCalc: https://www.slavasoft.com/hashcalc/
Having ensured that your JuiceboxBuilder-Pro installation file is not corrupt, the next thing I'd do is try the full uninstall/reinstall procedure noted as suggestion #11 in the forum post below. (Be sure to manually delete all files and folders listed in the forum post which may be left behind after an uninstall or a failed install.)

There are other hints and tips in the forum post which might help.
The suggestions in the post which I think are most relevant to your problem are #4 (regarding the location of the JuiceboxBuilder-Pro installation file), #9 (regarding anti-virus programs) and #10 (regarding the system clock).
With regard to #10, try setting your system clock back two years before attempting the install.
As unlikely as it sounds, it seems to have helped a couple of other users who have reported similar issues.
You can reset your clock to the correct time after the install.
I hope that these suggestions help you to successfully install JuiceboxBuilder-Pro.
Please let me know how you get on. Thank you.
The link in Readme to Adobe AIR is quite dead, but I think I found the right one on the new site.
As you have discovered, we have not yet repackaged the zip file with an updated 'readme.html' file but we have updated the link to the new AIR installer page (on Harman's website) in our online installation instructions here.
