It should "just work," as long as you allow the installations to go in separate folders, as they do by default. The last installed one will be the one chosen by default in VS projects.
Do you mean that you tried it and had a problem?
If you are integrating into Visual Studio, only VS2008 could work with both ifort versions. If on Windows 7, you will need one of the later versions of ifort 11.1.

Hello TimP,

i have the following installation:

Win 7 64bit (German)
vs 2008 standard (German)
IVF 11.1.048

if i try to install 12.1 update 7 i get the follwoing warning

Intel Composer XE 2011 installation can continue, but take note

Intel Visual Fortran Compiler Professional 11.1 Integration(s) in Microsoft Visual Studio* is already installed.
If you proceed to install, the 11.1 IDE integration(s) will be uninstalled and the Intel Composer XE 2011 IDE integration will be installed. You will be able to select the 11.1 product from that integration; however, you will be unable to use the Intel Visual Fortran Compiler 11.0 or 10.1 within the Visual Studio IDE (if it is currently installed).
Please note that Intel Composer XE 2011 IDE integration does not support 11.1 compiler in Microsoft Visual Studio* 2010, you will be unable to use 11.1 product from Microsoft Visual Studio* 2010.

Am i able to proceed and use me old installation (VS2008 and IVF 11.1.048) side by side with to new installation based on the new VS 2010 and IVF 12.1?

Thanks in advance
Frank

I think you are complying with the stated limitations (11.1 version recent enough to work on Win7, working with VS2008 which is compatible with both 11.1 and 12.1).
If you also have VS2010, that installation will work independently of the VS2008 integrations, but 11.1 of course won't be available under VS2010. The VS2010 shell which comes with 12.1 would not install when you integrate with a VS2008 or VS2010 standard (or both).
I recall a problem reported here once with German Windows, but you look to be in the supported range. So, if you had a problem, you have reasonable expectation of getting assistance either here or by submitting an installation problem report on premier.intel.com.

Frank,

The message is just warning you, as Tim said, that the latest compiler install is the only one that will work in Microsoft Visual Studio. You can still use the older version from the command line. Here is an article which shows which compilers work with which versions of Visual Studio.

You should be able to proceed with the install.

The message you quote can be a bit difficult to understand, as it is so "dense".

With the 12.1 VS integration, you can select 11.1 and later compilers from VS. You cannot select 11.0 and earlier compilers. This message relates only to the VS integration and does not affect command line use of older versions.
