Hi.
The latest version of JuicboxBuilder-Lite (v1.5.1.2) works OK for me (under AIR v33.1.1.744) using Windows 11 Pro x64 Version 25H2 (OS Build 26200.6725).
Here are some suggestions which might thelp:
Suggestion #1
First of all, you'll need to make sure that you use AIR v33.1.1.744 and not the very latest version of AIR (v51).
Harman, the developers of AIR, removed support for WebKit (the embedded browser that JuiceboxBuilder-Lite uses for the live preview of the gallery on the Customize panel) after v33.1.1.744.
Please see this forum post for further details: https://juicebox.net/forum/viewtopic.php?id=5318
You can download AIR v33.1.1.744 from the foot of the AIR download page: https://airsdk.harman.com/runtime
Here is a direct link for Windows: https://airsdk.harman.com/assets/downlo … obeAIR.exe
If you do have AIR v51 installed, please uninstall it first (via 'Control Panel -> Programs -> Uninstall a program') before installing AIR v33.1.1.744.
Suggestion #2
If you have any third-party anti-virus or security software running (such as Avast, AVG or Norton), try temporarily disabling it to make sure that it is not interfering with JuiceboxBuilder-Lite. (Please be sure to disconnect from the internet first and do so at your own risk.)
If you find that some anti-virus or security software is interfering with JuiceboxBuilder-Lite, then add JuiceboxBuilder-Lite to the software's whitelist. Please let me reassure you that JuiceboxBuilder-Lite contains no malware at all.
Suggestion #3
If you know the exact time of the application crash, then you could check the Windows Event Viewer to see if there are any entries in the 'Windows Logs -> Applications' or 'Windows Logs -> System' sections which give more information on the nature of the problem.
Please see this web page for more information on the Windows Event Viewer: https://www.howtogeek.com/123646/htg-ex … an-use-it/
Suggestion #4
There are other troubleshooting suggestions in this forum post which might help: https://juicebox.net/forum/viewtopic.php?id=5114
If you've not already tried it, try the complete uninstall/reinstall procedure (for both AIR and JuiceboxBuilder-Lite) noted as #11 in the post. (Just substitute JuiceboxBuilder-Lite for each instance of JuiceboxBuilder-Pro in the instructions. The procedure is the same for both Lite and Pro versions.)
I hope this helps.
Please let me know how you get on. Thank you.
