    Hi Christina,

    Gurobi 9.0.2 only supports R 3.6. I'll open a ticket for you in our online support portal to discuss this further.

    Best,

    Eli

    I am re-upping this to check if there's a Gurobi 9.0-2 support w/ R 4.0.0. This is going to super important in my choice of solver to teach next semester. 

    Thanks.

    Harish, they can send you some info about building the package. I still couldn't get it to work in Windows; I got about 90% of the way there, and am now using it on a Linux. You still need to build it with a Linux OS. It should be ok if you are programming-saavy. (I am not and needed a lot of help.) I don't know why they can't just send a link to unpack the package. I need it for an R package that no longer works without the updated version.

    Unfortunately, Gurobi 9.0.x still only supports R 3.6. Harish, we do have some options available (which Christina alluded to), though nothing would be well-suited for an entire class. Feel free to open a ticket in our online support portal if you'd like to discuss this further.

    Gurobi 9.0.3, released earlier this week, supports R 4.0.2.
