>>Try version specific ProgID

oGE = CREATEOBJECT("GoogleEarth.ApplicationGE.1")

>Generally How do i know that there is a .1 avaiable for automation ?

Fire RegEdit and look under hive HKEY_CLASSES_ROOT for particulat COM server, GoogleEarth.ApplicationGE in this case

>Or does all Automation are version independent without .1 and You can call specific version with '.' ?

Most COM objects have version independed ProgID but some don't.

>is there a chance of multiple versions being installed ?

Yes but it depends on the COM server.

>if so calling createobject without .1 which would be inistiated ?

Usualy the latest one.

When in doubt, use RegEdit to lookup info for particular COM server..
