On the jaLCDs forum you won't find any useful information because AC is using a special edition of jaLCDs.
You can download the latest version
here.
After installation you should check if your windows/system32 folder conatins the file aquaerolcd.dll.
Always start jaLCDs with the shortcut from you start menu or create your own which has to end with the paramter output=aquaeroLCD.jaLCD
Without this parameter jaLCDs will only give you a few error boxes.
Start jaLCDs and on the right side you will see two new icon in your taskbar. One of them is the AC logo and if you place your cursor over it you yould see the message 'jaLCDs aquaero interface ok'. Do a right mousecick on it and select 'Force aquaero LCD-Mode'.
Do a right mouseclick on the other logo (that green bar) and choose configs -> example.cfg
Now the display of your aquaero should show a few informations about CPU, RAM etc.
Do create your own config start the jaLCDs configuration. I highly recommend to open the example.cfg and save it under a new name. Creating a whole new config seems to be a bit buggy.
Now
