When the operating system restricts ExtendSim from registering as an OLE/COM server, the following issues occur:

• You get the error message Run-time error 429: ActiveX component can’t create object.
• Excel might not appear in the list of applications in the Data Import Export block.

For ExtendSim to be able to interface with Excel and other apps, launch ExtendSim with Administrative privileges so that it can complete the process of registering itself as an OLE/COM server. To do that, either right-click the ExtendSim application and select Run as Administrator or contact your IT or Admin and have them launch ExtendSim in your user account with the correct Admin permissions (once that happens, it won’t be required again).
