SolidWorks 2014 will be last release to support 32-bit OS
Found in the release notes for ePDM:
“SolidWorks 2014, including SolidWorks Enterprise PDM 2014, is the last release that supports 32-bit operating systems. SolidWorks 2015 and SolidWorks Enterprise PDM 2015 will not install on 32-bit operating systems.”
News to me.
