SolidWorks 2008 SP3.0 is now available for download. Thefollowing is a change to the Installation Manager to help improvethe experience:
The Installation Manager provides an estimate of disk space thatwill be used for new installs, major version upgrades and ServicePacks.
Prior to 2008 SP3, the disk size estimate when applying a Servicepack incorrectly showed the much larger size of a full install.This disk space estimation error did not affect what was actuallydownloaded, ie requesting a Service Pack would always download theSolidWorks patch file versus a full product download.
In SP3, applying a Service Pack now shows the appropriate estimateddisk space.
