Error: Interface not registered

[sd104400]

Hi,

I have this error when I tried to build/debug a Fortran file in Visual Studio 2019 I just installed. Nothing else is reported. I also tried "ifort" in command and it works, but not in VS.

In the VS Options, the right Fortran compilers for Win32 and x64 are selected. 

Does anyone know what the error means? Thanks!

Did you install VS2019 first and then Intel Fortran, as is required for the VS-IF integration to work, or in some other order? 

[sd104400]

I think I followed that order.  I also checked with intel oneAPI installer, and VS 2019 is integrated. Thanks.

I have the same issue.

Just changed from 17 to 19 and updated the 2021.4 Fortran.

When build my old project, this comes up.

When I try to build a MKL example, this is the error message:

Compiling the Fortran compiler identification source file "CMakeFortranCompilerId.F" failed.

Build flags:

The output was:

I've seen this occasionally over the years. Uninstall and reinstall the compiler.

I did a Repair. Now I can compile my program, but says: 

fatal error LNK1104: cannot open file 'ifconsol.lib'

[Steve_Lionel]

A repair might not have fixed everything. It now seems that you don't have library paths set up properly. Go to the following Tools > Options page and click Reset. Click on the x64 tab and click Reset there too, then click OK.

After reset, still can't open that lib.

Here is my Libraries setting:

I uninstalled and reinstalled the compiler. It works now. Thank you very much.
