Macintosh 12.5.1 Web Updaters
VectorWorks 12.5.1 was released for both Mac and Windows as a downloadable updater and DVD installer on January 9, 2007. Shortly after the release, NNA discovered a problem which could cause a crash during AutoSave and some other less serious problems only on the Macintosh. We released a revised Macintosh updater of our 12.5.1 product on January 19, 2007. You can determine which version you are using by examining the "About VectorWorks" dialog (available from the VectorWorks menu on Mac versions). If your version states 12.5.1(65397) then you are using the latest release. If your version states 12.5.1(64620), then you are using the original 12.5.1 release and you should either re-install using your DVD and choose to apply the available online updates, or download and apply the revised online updater.
