Hello,

Thank you for your post.

If no window appears this indicates you may have corrupt installation. Please use the steps provided below to uninstall/reinstall NinjaTrader. With this procedure you will not lose any Workspaces, Charts, etc.

• Close all running applications.
• Then from the Start menu select --> Control Panel --> Add and Remove Programs.
• From Add and Remove Programs select NinjaTrader 7 and click Remove.
• Then you will need to clear your internet browser cache and history. You will clear this from within your internet browser (with IE, Tools-->Options, delete cookies and files, clear history).
• Reboot your machine.
• Once these steps are completed, download NT 7.0.1000.22 from the link below:
