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!

Hi - thank you for your message, we are working to try to resolve the problem. Please note that we've been having all sorts of difficulties with building portable binaries for Mac M1/M2 systems. Applications have to be code signed etc and doing so isn't working for reasons best known to Apple at this point, and we are waiting on tech support from them for this issue.
We're not sure why the binaries aren't in the right place for the windows system - do you have version info for that issue?
Finally, note that the other optimizers are usually fine substitutes for NPSOL - our test suite of hundreds of scripts finds only negligible differences between NPSOL, CSOLNP and SLSQP.
