Service Packs are free to download. They contain changes, enhancements and fixes since the release was first shipped.
We recommend downloading a Service Pack if it is newer than the version you are running. You can check if a Service Pack is newer if the build number on the 'What's in the Service Pack' page is higher than the build number in your software. You can find the build number in SIMUL8 under the 'Help' section on the 'File' menu.Upgrade to SIMUL8 2020
* If you run a special "corporate" edition of SIMUL8 that has features unique to your company, don't use these upgrade files - your company's special features will go away! If in doubt talk to your company's internal SIMUL8 Team or email us at
