I am creating a Simulink model for TwinCAT and while generating the code I always run into an error, namly:
The call to TwinCatGrt_make_rtw_hook, during the after_make hook generated the following error:
Project preparation failed
The build process will terminate as a result.
Caused by:
  • Project preparation failed
I searched the internet for an answer but can't seem to find any. I also tried creating a completely empty model and just doing a simple addition and I get the same error. The TwinCAT libraries should all be installed and the matlab libraries aswell.
Does anybody know how to solve the error?

Sorry for the long wait, I actually got the problem again and finally solved it again. It depends why the preparation failed. In my case it wasn't finding the compiler:
I then found out that my TwinCAT 3 was not linked to VisualStudio anymore and thus could not find the compiler, To make sure this is the case check this:
If the VS 2019 is missing you have to deinstall TwinCAT 3 and then install it again making sure the Visual Studio box is ticked during the installation.
This should solve the issue. I hope I could help
