Hi,
When I was working hands on the CTP8 environment of Dynamics AX 7, I mistakenly created two Models (Application Platform Customized and dfsfsd) both referencing existing package "Application Platform". Since then a blocking error popup is coming which says, "Some models have duplicate ids..."
Please see the image below:-

This blocking error is coming everywhere, on every button click in the Visual Studio !!!
I understood I needed to delete the 2 models and that will fix the issue, but I could find any option to delete the model from Visual Studio. Then I tried using axutil from C:\Packages\Bin location. But this is what it says:-
ERROR: Microsoft Dynamics AX 7.0 not found in the registry. Please specify the /db switch.

Can you please help me what database value I need to specify here for the CTP8 environment? I saw that its of the following format:-
axutil list /db:<database>
And what is any (if any) better way to delete the erroneous models?
I am surprised the AX 7 environment is so unstable, a simple mistake by the developer can bring it down.
