Hi,

I am using Windows system and I have downloaded the gurobi successfully. 

Then I try to install R package in RStudio. 

When I run library(gurobi), I get the following error Error: package or namespace load failed for ‘gurobi’ in inDL(x, as.logical(local), as.logical(now), ...): unable to load shared object 'C:/Users/peiza/AppData/Local/R/win-library/4.5/gurobi/libs/x64/gurobi.dll': LoadLibrary failure: The specified module could not be found.

  Thanks, Riley! I have resolved this issue! I don't know why. I just re-run the code “library(gurobi)”, and this time it returns no error. Thank you so much!

  All the best,

  Peizan
