loading rLingo package for R

Question

Working with R (ver 3.4.1) and Lingo (ver 16), attempting to install rlingo package using the provided direction within Lingo documentation via command prompt.

I get the following error message:

I checked the Lingo directory and the 'install-rlingo' batch file is there. Any help in correcting the installation issue is greatly appreciated.

WE found the solution to this issue. Updated our LINGO application to ver 17. The rlingo package loads properly now.
