How to update the path of motionsolve bin directory?

User: "sudo"

I am getting this error when running a simulation in twin activate:
"Unable to load MotionSolve interface dll during block initialization"

I tried to run this command in command window:
GetMotionSolveBinDirectory()

It outputs this:
ans = C:\Program Files\Altair\2024.1\hwsolvers\motionsolve\bin\win64


It is pointing to the version 2024 but I have updated my motionsolve to version 2025 and the bin folder is now located inside the 2025 directory.

How can I update and tell twin activate that the bin directory of motionsolve is at

C:\Program Files\Altair\2025\hwsolvers\motionsolve\bin\win64 ?

    Hello @sudo

    I hope you have installed same version MotionSolve/MotionView and in Activate make sure you have setup the MS/MV path in File->Preference->path. Here is the snapshot
    It can be the 2025 version path in your case.
