Long time ACP along with TheSkyX user here. Please help fix this.

I reinstalled ACP 8.3 and Planner on new PC (Windows 11) in my observatory. ACP works but TheSky Plan Capture will not. It gives message "Neither TheSkyX nor TheSKy6 appear to be installed on this system". I redownloaded from your website several times but it gives same error.

What is going on? Please help.

thanks -- Rex Parker
