Hi Manoj,

Just tested the web switch via MaximDL and it worked well. However, in running digitalloggerssetup.vbs, after testing the switch as already mention, I got the same error related to line 21 "Set DLWPS = CreateObject("ASCOM.DigitalLoggers.Switch")"

Running the vbs script separately is not working at all.

It seems that the COM object was created only when installing the driver but vanished after switch properties were saved. My two cents.
