New Post: Library in a different folder in vb

Thank you, I will try this, i did'nt see your last post before posting.

Edit : I translate it in a vb.net version and : I have to add this or else it doesn't work. And also not use engine.initialize() ? it is not recognized.

REngine.SetDllDirectory("C:\Program Files\R\R-2.15.2\bin\i386")

And finally, it doesn't work, same error in the same place...

Here is my code :

Dim envPath = System.Environment.GetEnvironmentVariable("PATH")
        Dim rBinPath = "C:\Program Files\R\R-3.0.0\bin\i386"
        System.Environment.SetEnvironmentVariable("PATH", envPath + Path.PathSeparator + rBinPath)
        REngine.SetDllDirectory("C:\Program Files\R\R-2.15.2\bin\i386")
        Dim engine = REngine.CreateInstance("RDotNet")
        engine.EagerEvaluate("library(drc)")
        engine.Evaluate("?drc::actimL")
        engine.close()
