How to keep two versions of Intel Fortran compiler on windows 10?

[Fortran10]

As intel has discontinued the ifort compiler in the new release, I would like to upgrade to this new version. However I do not want to remove the previous version that contains ifort compiler. So my concern is how to keep both versions together? Which commands should I use to invoke the specific version of the compiler?

hyper-v or equivalent or another computer

Windows or Linux? New installs do not remove previous versions. From a command prompt you can invoke the setup batch file of your preferred version. I'm not sure if Intel will remove access to ifort  in the Visual Studio interface. If you have a separate install of an older VS with ifort enabled, you can unselect that version when the Intel installer prompts you about VS integration.

There are no changes to the VS interface in the 2025 ifx release; if you have had ifort previously installed on the system, you can access it.
