registry key: 'NinjaTrader' is missing

[jjanguda]

I had no problem running NT7 without any issues. (I also installed NT8).
But I just found that I can't run NT7 due to a registry key issue. Attached the image as a reference. How can I fix this matter?

BTW, NT8 is running properly.

I would appreciate your help.

Thank you.
