Not sure which package you want to upgrade to? Check the ExtendSim Product Advisor.        

Depends on the type of models you're building. If you're building discrete event models, upgrade to ExtendSim DE. If you are using the blocks from the Rate library in your models or want to use the new Reliability components, upgrade to ExtendSim Pro.

For more details on which package may work best for you, use the ExtendSim Product Advisor.

ExtendSim 10 is upwardly compatible and will read in models built in legacy ExtendSim versions 9, 8, and 7.

If you created a custom library in a legacy version, before opening the model using the custom libraries, open the custom library. Go to Library > Library Tools > Compile Libraries... Select your custom library and click Compile Selected Libraries. This will recompile the library creating an ExtendSim 10 library with a .lbr extension. Then, open the model in ES10.

Note: ExtendSim 10 is not backwardly compatible. Models and blocks you build in ExtendSim 10 cannot be read by earlier versions, such as ExtendSim 9 or ExtendSim 8.

You cannot copy objects in models (graphics, text, hierarchical blocks, databases, etc.) from release 9 or earlier directly into ExtendSim 10. Instead you must open the model file in ES 10. Then, ExtendSim will convert it to an ExtendSim 10 file.

Choose About ExtendSim under the Help menu to open the ExtendSim start up screen. The bar at the top shows you which ExtendSim release you are using. If it does not say ExtendSim 10.0.2, you should download the most current release.

Use the Trial version of ExtendSim for your update. Download the Trial version of the package you purchased and install over your current installation. When you restart ExtendSim, you will be running 10.0.2.
