Post subject:  Cannot Launch HPC Simulator - Unable to launch the applicati

I am a new user to HPLC simulator; I saw your presentation at ACS San Francisco, 2014 and am greatly interested in using this tool in my courses. However, after downloading the software (none of my browsers seem to be loading the app within the browser), I get an Application Error: Unable to launch the application. I have updated my Java program to the most recent version. Below are the Launch File and Exception notices I have received from the Java Launcher. Thank you for your time!

Hi Eric,

Thanks so much for sending the bug report. Sorry it took me a while to reply. I thought I'd already replied, but I apparently hadn't pressed the submit button.

I'm not quite sure what's going on here. I can't reproduce the error on any of the computers I have access to. Could you tell me what operating system you are using and whether it is 32- or 64-bit?

Thanks,

Paul

Hi,

I really want to use this for my class but I'm also unable to launch the application.
I'm using a PC running on Windows 7 (32-bit OS). I have Java 8.25 currently installed.
Thanks in advance!
