It's good practice to first copy your Ninjatrader folder into Ninjatrader Backup so you have a copy of all your files, just in case. Also note that NT8 stores its sound files under C:\Program Files (x86)\NinjaTrader 8/sounds.

Then remove (uninstall) any Remek! products from Windows Control Panel before running the latest installer(s) of our products. 

ALWAYS RETAIN A COPY OF YOUR INSTALLATION FILE: store a copy in a safe place, you will need it one day when you want to re-install your product, or install your product on a new machine. 

Please refer to the ReadMeFirst file in the individual folder(s) of your product(s) under Ninjatrader 8/bin/Custom for further details on individual products.
