It’s official – if you plan to upgrade to the latest and greatest version of SolidWorks next year, you will NOT be able to do so on Windows XP.
SolidWorks 2012 software (including CAD, Simulation, Sustainability, and Enterprise PDM) will be the last release that supports Windows XP. This action is being taken as a follow up to Microsoft’s retirement of the Windows® XP operating system in April of 2009. SolidWorks 2013 will not install on Windows XP. For additional information please refer to the System Requirements page on the corporate website.
