Parallel Studio XE 2015 for Linux environment setup bug

New Contributor I

After installing Parallel Studio XE 2015 for Linux, or any of its updates, setting the environment by calling /install_directory/product_directory/ with either 'ia32' or 'intel64' creates a PATH which starts with '/install_directory/bin' folowed by some '/install_directory/product_directory/bin' directories. This works fine as long as no further Parallel Studio XE 201x for Linux product is installed afterward, but as soon as some Parallel Studio XE 201x product for Linux is subsequently installed it updates '/install_directory/bin' to point to its own executables. This makes it impossible to use Parallel Studio XE 2015 for Linux from the command line using its environment setup as soon as some subsequent version of Parallel Studio XE for Linux is installed. Of course the bug should be fixed by adding the '/install_directory/product_directory/bin' directories to the PATH before the '/install_directory/bin' directory. Since Parallel Studio XE 2015 for Linux is an old release this bug has evidently never been caught, but it clearly makes it impossible to test this old release once a newer Parallel Studio XE for Linux release has been installed in the same directory structure.
