Hello @pspen,   Most likely, you don't have SAS installed on your laptop, but you are using an interface such as SAS Studio or SAS Enterprise Guide which connects to a server-based SAS installation. That server cannot access your local C: drive, hence the error. If you can copy and paste the code from nlmeans.sas and nlest.sas into the program editor of your interface and then submit it from there, this should be the easiest solution. Otherwise you need to upload the two .sas files to the server, e.g., to a location where other .sas files reside that you've been working with, so that the server can access the code (e.g., again via %include, but with the new server path replacing the local "C:\Users\..." path).   Good luck!   Finally, let me repeat the hint from my previous post in this thread: @FreelanceReinh wrote: Hint: Generally, it is much better to open a new thread than to add questions to an old one (like from 2019), which only a few people will read. So, if you don't succeed with the copy/paste or upload approaches suggested above, please open a new thread so that people using SAS Studio or SAS Enterprise Guide can further assist you. ...

As noted in red at the top of the documentation for the NLMeans and NLEST macros, these macros should be directly callable in SAS 9.4M6 or later. But if, for some reason, either of these is not found, then they can be downloaded and defined in your SAS session as discussed at the links provided above. Note that the NLMeans macro calls the NLEST macro so both are needed. You can check their availability in your SAS session and check their versions using the following calls. I suggest using the latest versions which, as noted in their documentation, are 1.9 for NLEST and 1.4 for NLMeans.  %nlest(v) %nlmeans(v) ... View more
