Roadmap for platform support

Support for installing and running the Thermo-Calc software package on Windows XP has been dropped as of the Thermo-Calc 4.1 version release.

Support for installing and running the Thermo-Calc software package on all 32-bit platforms has been dropped as of Thermo-Calc 2018a. Users with a 32-bit platform installation are therefore advised to migrate to a 64-bit platform.
