What is the difference between a release version and a service pack, and where can I download them?
- Release versions are independent program versions which can be updated with service packs. - Service packs include new features and bugfixes. They can only be used to update the corresponding release version, which means that e.g. service pack 11.00-06 requires a base installation of PTV Vissim 11. The updates are cumulative, meaning that the latest service pack includes all earlier ones.
