Hi!
I have been trying to install the OpenMx Team's build of OpenMx with the NPSOL optimizer, using the following line as per instructions (https://openmx.ssri.psu.edu/installing-openmx):
source('https://vipbg.vcu.edu/vipbg/OpenMx2/software/getOpenMx.R')
I have tried several times and with several R versions (4.1.3, 4.2.3, and 4.3.1), but I always get the warning that the package ‘OpenMx’ is not available as a binary package for this version of R (see full warning message attached).
What is even more strange is that I am certain that OpenMx with NPSOL has previously worked for me with R versions 4.1.3 and 4.2.3. I have recently updated my MacBook (Intel core) to Ventura 13.4.1, but I don't think it has something to do with that as I am having the same problem when trying to install OpenMx with NPSOL in a Windows environment.
I don't understand what is happening. Please help!
