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?

Could you explain in details how to fix the problem pls?

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
