FlexSim 2019 Update 1 Beta Available

FlexSim 2019 Update 1 Beta is available. (Updated 11 April 2019)


The 15-Mar beta installer has a bug that causes the current installer to hang during the Cleaning Up stage when upgrading from the 15-Mar beta to a newer beta version. We have resolved the issue for future installers, but to avoid the error now, uninstall the 15-Mar beta using Add/Remove Programs before installing the new version.

To get the beta, log in to your account at, then go to the Downloads section, and click on More Versions. It will be at the top of the list.

If you have bug reports or other feedback on the software, please email [email protected] or create a new idea in the Development space.

Known Issue

The step/iges/jt importer was not working correctly with the 15-Mar Beta. It was displaying the following error when it tries to connect to the OCCT.dll, and then the shapes were not loading correctly:

We've fixed this bug in the 29-Mar beta.

Hi all,

There seems to be a bug that crashes FlexSim in the UnLoad task in ProcessFlow. When you sample a task executer or an item FlexSim crashes. The two fields are also not filled in when you dropped the activity in the ProcessFlow.

Probably you already know: the help on Calculated Table isn't updated and the help button in GUI doesn't work. Please, don't forget it! Thanks!

Known Issue

The shapes of entrance and exit objects when opening a previous model aren't showing. This has been fixed in the 29-Mar beta.

Related FYI

The entrance and exit objects can now be found in the Prop object list of shapes rather than the list of Location shapes.
