Integrating both Fortran 2019 update 5 and 2019.1 with Visual Studio 2019?

[David_Billinghurst]

I am currently using Fortran 2019 update 5 (for Windows) with Visual Studio Professional 2019 version 16.4.5.  We would like to use this version of the compiler while we test the 2019.1 release.

Can I install Fortran 2019.1 and integrate both Fortran  2019u5 and 2019.1 with Visual Studio?  I tried on an test machine and can only access the newest compiler.  When I look in Tools > Options > Intel Compiler and Tools > Visual Fortran > Compilers, the only option for Selected Compiler is Intel(R) Visual Fortran Compiler 19.1.0.166 [Intel(R) 64].

It appears to work alright in Visual Studio 2019:

Recheck what you did and retry

Explained in detail here. You need to have both compiler versions installed in order to see this.

Thanks for the confirmation.  It worked for me with VS2019 and Fortran 2018/Fortran 2019.  I will retry.

An uninstall/install of both compilers fixed this on my test machine.  An install of 19.1 on my main machine worked OOTB.
