Issue: Microsoft* Visual Studio 2012 is supported by Intel® Parallel Studio XE 2017. It is not supported by Intel® Parallel Studio XE 2018. Wrong Intel® Fortran compiler version displayed in Microsoft* Visual Studio 2012 in case both Intel® Parallel Studio XE 2017 and Intel® Parallel Studio XE 2018 are installed on the same system with Microsoft* Visual Studio 2012.
It may be observed while opening "Tools > Options > Intel Compilers and Tools > Visual Fortran > Compilers".
The 'selected compiler' may be shown as "Intel(R) Visual Fortran Compiler 18.0", which is not correct.
Once the compilation process is invoked the correct compiler version is used. The output window shows a wrong compiler name "Intel(R) Visual Fortran Compiler 18.0". For example, there are both 17.0 Update 4 and 18.0 compiler versions installed:
1>------ Rebuild All started: Project: Console8, Configuration: Debug Win32 ------
1>Deleting intermediate files and output files for project 'Console8', configuration 'Debug|Win32'.
1>Compiling with Intel(R) Visual Fortran Compiler 18.0.0.118 [IA-32]...
1>Console8.f90
1>Intel(R) Visual Fortran Intel(R) 64 Compiler for applications running on IA-32, Version 17.0.4.210 Build 20170411

Environment: Both Intel(R) Parallel Studio XE 2017 Update 4 and Intel(R) Parallel Studio XE 2018 are installed, Microsoft* Visual Studio 2012 is installed
Root Cause: A root cause was identified and will be fixed in the upcoming compiler versions.
Workaround:
The user should select “Intel(R) Visual Fortran Compiler 17.0” at the 'Select compiler' option at "Tools > Options > Intel Compilers and Tools > Visual Fortran > Compilers". Then the correct name and compiler will be displayed as expected:
1>------ Rebuild All started: Project: Console8, Configuration: Debug Win32 ------
1>Deleting intermediate files and output files for project 'Console8', configuration 'Debug|Win32'.
