STEM Installation Guide new

Updating STEM

Starting with version 1.4, you can use the update mechanism built into STEM to perform upgrades without re-downloading the full installation bundle. Most of the time, this means you don't have to re-download the large denominator data sets packaged in STEM or have to export and import your scenarios.

1. Verify the computer is connected to a network and launch STEM

   If STEM is already open, save all edited files and stop any running simulations

2. Open the Help Menu and choose Check for Updates

   

3. Wait while STEM contacts the updates server and checks for new versions
   • If no updates are available, a message saying No updates were found will appear. Click OK to return to STEM.
   • If an update is available, the Available Updates wizard will appear
4. On the Available Updates page, verify STEM is selected, and click Next

   

5. Verify the list of items to be installed is correct and click Next
6. Review the the licenses of the software being installed to verify you still accept

   If you accept the terms, select I Accept the terms of the license agreements and click Finish

7. Wait while STEM downloads and installs the updates
8. If prompted with a security warning about installing unsigned software, click OK
9. When prompted to apply changes, verify all open files are saved and click Restart Now
10. STEM should automatically restart. If not, relaunch it manually.

Updating to Latest Integration or Milestone Build

   On Mac OS X, Preferences is under the STEM menu

3. In the Preferences window, expand Install/Update and select Available Software Sites
4. Under Available Software Sites, Click Add
5. In the Add Site dialog, enter the appropriate Name and Location

   For weekly integration builds:
