ST-Runtime Support Files

The STEP AIM and IFC BIM libraries contain embedded EXPRESS data dictionary information and can be distributed without any additional support files.

Programs that do not use either of these libraries need compiled EXPRESS schemas at run-time to function properly. To simplify release engineering for such programs, these support files are collected into a redistributable package called ST-Runtime.

ST-Runtime is included with ST-Developer, but newer versions may be available. The latest versions in MSI, MSM, and Zip form are listed below. MSI is a stand-alone Windows installer. MSM is a merge module so you can add ST-Runtime to your own Windows installer. The zip file is used for all other platforms.

ST-Runtime 18.0 MSI installer 18mb [download]
MSM merge module 18mb [download]
Zip archive 18mb [download]
