Error: Run time error 429 ActiveX Component Cannot Create Object

Error Message

When starting up the ArcExplorer-Java Edition 2.0 application, the following error message is immediately displayed:

"Run time error 429 ActiveX Component Cannot Create Object".

Cause

The cause of this problem is that one or more components that can be registered(OCXs or DLLs), which are required for ArcExplorer-Java Edition to run properly, were not successfully copied onto the machine or were not properly entered into the Windows Registry. By design, the user should not have to do this manually. The setup program should have done this all automatically.

One common cause of this is that the user tried to start ArcExplorer-Java Edition 2.0 immediately after installing the application, instead of first restarting the machine. ArcExplorer-Java Edition requires a reboot after installation so that the components can properly register.

Solution or Workaround

1. Reboot the computer, then try starting up ArcExplorer-Java Edition. If no error is displayed, then the problem has been resolved.
2. If the error message is still displayed, then register the 'mo20.ocx' file:
   
   A. Navigate to Start > Run. Type cmd and click OK.
   B. Type the following command and press return:
   
   

   Code:
   regsvr32.exe "C:\Program Files\Common Files\ESRI\mo20.ocx"

   
   If it registers successfully, start ArcExplorer-Java Edition again. If no error is displayed, then the problem has been resolved.
3. If the error message is still displayed, then register these additional files with 'regsvr32.exe' using the same method above above:
   
   In the \Program Files\Common Files\ESRI folder:
   
   mo20.ocx
   aiimage20.dll
   cad20.dll
   coverage20.dll
   momrsid.dll
   mosde80.dll
   mosde302.dll
   shape20.dll
   vpf20.dll
   
   In the ArcExplorer 2.0 installation folder:
   
   aeclient.dll
   aecommon.dll
   aeinet.ocx
   aelegend2.ocx
   aemo2.dll
   aeprint2.dll
   inetlegend.ocx
   scalebar.ocx
   
   

   Note:
   As an alternative method to running the 'regsvr32.exe' from the command prompt and typing each command manually, create a shortcut on the desktop for the 'regsvr32.exe', and one at a time, click-and-drag the above files onto that shortcut icon.
   
   Optionally, some Windows machines are configured to give you access to registering DLLs and OCXs by providing a 'Register' menu item on the context menu, accessible by right-clicking the file name.
