Not open solution from ninja trade on visual studio 2019

[synthhokie]

It opened Visual Studio 2022 which I had forgot I installed when trying to figure this out. But that previous resulted in an error as well and now is fine.

Hello synthhokie,

Whew, I'm glad that worked. Because I was out of ideas.

Hello steinberg123,

Currently, NinjaTrader has released 8.1.4.1. While the previous release 8.1.3.1 is still available for download from the Account Portal, any prior releases would not be available.

However, visual studio 2019 and 2022 can be used with 8.1.4.1.
