Only one version of Intel Parallel Studio XE can be integrated with any one version of Microsoft Visual Studio* at a time. Therefore, if you have Intel Parallel Studio XE installed on your system, and then install a different version alongside it, the newly installed version will be integrated into Microsoft Visual Studio* in place of the previously installed version. This means you will see the newly installed Intel Parallel Studio toolbars, menu items, and so on.
To control which version of Intel Parallel Studio XE you use with Microsoft Visual Studio*, you will need to change the version of Intel Parallel Studio XE that is integrated with a particular version of Microsoft Visual Studio*. This will need to be done for each component of Intel Parallel Studio that you have installed.
Note Up to three consecutive versions of the compiler (Intel Parallel Studio XE 2018 Composer Edition) may be integrated into the same Microsoft Visual Studio* version. In this case, you need to install compiler versions one by one starting from oldest. The integration from the latest compiler version will be installed last. For example, it is possible to install Intel Parallel Studio XE 2016 Composer Edition, and then version 2017 and 2018. Integration from the latest 2018 version will be installed and it allows switching between 16.0, 17.0, and 18.0 compiler versions. However, it is not possible to integrate Intel Parallel Studio XE 2015 Composer Edition, 2017, and 2018 versions with a particular version of Microsoft Visual Studio*.
