I can help you with this.
Tell me the steps you are following, are you using Visual Studio 2022 and have you added all the indicator project references?
If you are getting the error with the WAE Explosion indicator then this could happen if you do not open with Visual Studio 2022, it should look like this.
I would build all the indicators, open the cBot project, make sure the project has a reference to each indicator and then build the cBot.
You can add indicator references from the cTrader Automate application as usual.
If you get stuck just post on here again.
