Hello, My issue was solved. I want to write here the resolution for everybody. The issue was solved after Windows 10 Pro update. So, the problem was not coming from Codesys but from Windows 10 Pro. I have a retail licence of Windows 10 Pro. I had recently installed Windows 10 Pro on my virtual maschine running on macOS Monterrey. When Windows 10 got selfupdated I found that Codesys is running OK. Thank you to anybody and to Codesys for this fantastic piece of software.
I just installed Codesys v3.5 SP18 Patch 2 on Windows 10. I also installed the frameworks .NET as required by the installer. When I try to create a new project I get 10 errors in the Codesys GUI. Standard Project > Control Win V3 x64 Errors Precompile C0046: Identifier 'DED.CAADiagDeviceDefault' not defined C0046: Identifier 'DED.INode' not defined C0046: Identifier 'g_itfRootINodeInst' not defined C0046: Identifier 'IoConfigTaskMap' not defined C0046: Identifier 'IoConfParameter' not defined Errors...
