I've installed Mathematica new releases before on my PC.

This is the first time it asks to restart the PC at the end of the installation of V 13.1. This is on windows 10.

enter image description here

The question is, why in this version one needs to restart the PC?

Just curious that is all. It not a big deal to restart the PC. Just wondering why only this happened in this version and in none of the earlier versions of Mathematica as far as I remember.

  • $\begingroup$ @Nasser What is the release id for your version of 13.1: AssociationMap[SystemInformation[#,"ReleaseID"]&,{"Kernel","FrontEnd"}]? $\endgroup$

    $\begingroup$ @user13892 will let you know once I restart my PC. I have not been able to do that yet, as I am running a program which takes days to finish something. Once it is done, will let you know. $\endgroup$

13.1 and later are using the dynamic version of Microsoft's C++ Runtime library. If another application was using it when the installer was run, then you might need to reboot your machine.
