Celestron ASCOM Port Issue

[cken (Jack)]

Hi there,

Hope someone can help.

I 'd like to controll my CPC1100 from computer.

I installed ASCOM Platform 6 and the driver "Celestron Unified (6.1.7350, Feb 2020) Telescope & Focuser".
But when I try to configure the Celestron telescope driver, there are no ports listed. Then I ticked "Show All COM Ports", it shows COM3 and COM4.
I know it's COM4 after checking Device Manager so I choose COM4 and a error masseage pops out:

CheckDotNetExceptionsASCOM.Celestro n.TelescopeConnectedSetSystem.Unaut horizedAccessException: Access to the port 'COM4' is denied. (See Inner Exception for details)

I tried uninstall and reinstall, still same problem.


MY equipment:
Windows 10 Pro
CPC 1100 DeluxeHD with/without wedge
Celestron Focuser Motor
Connection: CPC---Hand Controller---Usb---Computer

I tried change usb cable, and tried running AScom as administrator(it doesn't allow)

Am I missing anything?
