On Linux, uninstalling older version of compiler damages current version

When I install new compiler version, old one is maintained.

Maybe installer should ask the user what to do about older versions (delete/keep).

If I then uninstall the old version using

... intel/parallel_studio_xe_2019.4.068/uninstall_GUI.sh

(depending on the version I am uninstalling)

it also damages the current installation, for example

... intel/bin/compilervars.sh

also gets deleted and compiler no longer starts.

I had to use repair tool from the GUI installation to fix the currently installed version.

I am using OpenSUSE 15.0, 64 bit, i7-5820K, but it should not matter, since the bug is clearly in the unistallation tool.
