I am getting the following error, which I believe to be with nlrx, because the model will run in NetLogo now that the R extension from NetLogo issues have been worked out. The r.jar and jna-4.2.2.jar files are both there. The error is generated almost immediately when I try to start the simulation in R.

R's nlrx package is running the simulation in Netlogo which uses a nonlinear solver from GAMS in R using NetLogo's R extension to choose activities. I have successfully used the model in a linux environment, so the process works. The NetLogo model will run in NetLogo which I take to mean the R extension is properly setup.

Any ideas?

The error is generated almost immediately when I try to start the simulation in R.

You have failed to install the Microsoft Visual C++ 2013 Redistributable on your system. Be sure you install both the 32-bit and 64-bit versions. I should point out that Visual C++ 2013 is not binary compataible, which means you must provide the exact version of the library, that NetLogo is actually looking for.

Visual C++ Redistributable Packages for Visual Studio 2013

Update for Visual C++ 2013 and Visual C++ Redistributable Package

  • Since I cannot determine what version of msvcr120.dll NetLogo is expecting, I have linked to two different versions, you should install the one that is required. There might be more than those two versions of msvcr120.dll that exist, you will have to determine, what version of the file is required. Based on the information provided I cannot determine that.

  • Thank you! I will try this when I get back to the office. I had installed Microsoft Visual C++ 2015, but not 13. What information would you need to determine which version is required? Commented Aug 14, 2019 at 18:08
  • @jjhold - I am not actually going to list every version of that particular library (it would be helpful to anyone but you). You would have to determine that yourself. The list of depencies for NetLogo would be a good start. Commented Aug 14, 2019 at 19:48
  • — you should read before you snark. I asked how. I wanted to know how to know in the future. I’m glad you get your jollies by making snarky demeaning comments. Good job with achieving the stature in life to troll these forums. I’ll Commented Aug 15, 2019 at 21:43
