I’ve installed the Harmonic Pattern Scanner on cTrader Desktop (demo account, latest version). When I click the “Settings” button, I get a blank white window. After enabling WebView2 and installing .NET 6 runtime, I now get a system error:
System.NullReferenceException: Object reference not set to an instance of an object. at Syncfusion.Windows.Forms.MetroForm.UpdateSystemButtonsImages()
System.NullReferenceException: Object reference not set to an instance of an object.
at Syncfusion.Windows.Forms.MetroForm.UpdateSystemButtonsImages()
I’ve tried all the following:
Reinstalling the bot
Launching cTrader as administrator
Ensuring full access permissions
Installing all required runtimes
Nothing resolved the issue. The bot UI fails to render.
Please advise if this is a known bug or if an updated version is available.
