I installed the game, ran the testpage, but it opens in notepad (or another program than my browser), shouldn it open in a browser?
You might not have a browser installed, please verify you have Microsoft Internet Explorer or another browser. Browse to your BioExplorer directory, and into the Flash\NeuroFlasher\NeuroPuzzles…\ directory, where you will find the index.html file. Right-click (on some system you must hold ctrl or shift) on the index.html file and choose the option: Open With…. From this menu, choose Choose program. A list will show, select Internet Explorer and check the ‘Always use the selected program to open this kind of file’ option. Click OK. Note that this is only required to either run the testpage, or install the latest Flash Player over the web. You do not need to have Internet Explorer to actually run the game in BioExplorer, and you can always install the Flash Player from the accompanying CD-rom.
