Unable to Import NinjaScript Add On: Unhandled exception

[mattbsea]

Hello,

I'm trying to install a new Add On. When I select Tools -> Import -> NinjaScript Add On..., I get an error window with "Unhandled exception: Value does not fall within the expected range"

How do I fix this?

Hello mattbsea ,

Thank you for reaching out.

I recommend a repair to your NinjaTrader 8 platform to try fixing this error. To complete a repair, do the following:

• Shut down NinjaTrader 8
• Go to your computer's Control Panel > Programs & Features (Note: search for 'Control Panel' to find it within the Windows Start Menu. This will be a different window than the Settings page)
• Left-click once on NinjaTrader 8 > select 'Repair' above the list of available programs
• Restart the platform after it finishes repairing, and test for this behavior again.
• Here is a video I made for your reference: https://www.screencast.com/t/5RH7MjuaQiG

Please me know the results of this test. I look forward to your response.
