Hi every one,

I will appreciate your help regarding lean engine release update, i have for a long time managed to build my lean engine succesfully and used it smoothly on my windows pc, but some reason during the latest releases it started targeting .Net 4.6 and build failure in quantconnect.toolbox, quantconnect.launcher due to missing refernce in assembly, i have tried to run nuget but dont know which package to update and how to use it.

Any help will be greatly appreciated.

Regards

Hi Essam Saed ,

Are you running the latest version of Lean? Does your system have .Net Framework 4.6.2?
I would recommend getting those and rebuild with a clean version of Lean (remove all packages and let nuget fetch them again).

Dear Alexandre Catarino

Thanks for your reply, I have tried as you suggested but still, I receive the same errors,

I have downloaded the latest lean version and I do have .Net framework 4.6.2 but i don't know why i receive this build error any other suggestions.

Thanks

Hi Essam Saed ,

This warning message:
warning MSB3270: There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "C:\Users\essam\source\repos\Lean\Research\bin\Debug\QuantConnect.Research.dll", "AMD64". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

gives us a hint that you might be compiling Lean with the wrong processor architecture. That's why I asked you to get the latest version since a similar issue was solved by #4593...

Do you know which Lean version had worked on your computer? The Net Framework upgrade can be the cause, but it was merged mid-May. However, it's likely an issue with your system, and probably you will have to do a major clean up (remove and reinstall Net Framework, Visual Studio, etc).

Dear Alexandre Catarino

Thanks very much for your suggestions, i have tried it and reinstalled visual studio and lean from scratch and it worked greatly

Thanks
