When I try to create a new Syncfusion project in Visual Studio 2017 (Windows 10) I have this error:

Parametro non corretto. (Eccezione da HRESULT: 0x80070057 (E_INVALIDARG))

I send you the Activity Logs, but there is not Error log file in the solution file location.
I was trying to create an ASP.NET MVC (EJ2) project.

Hi Chiara, 
Thank you for sharing the requested files.  
We have checked the shared log file and found that there is no error related to Syncfusion. So, we suspect that our extension was not installed properly on your machine. Please try the below steps and let us know if this helps you.    
1. Open Visual Studio 2017.     
2. Open Manage Extensions by navigating to Tools -> Extensions and Updates       
3. Select the Installed tab on the left side and type “Syncfusion” in the search box.      
4. Choose ASP.NET MVC Extensions - Syncfusion and click uninstall.   
5. Once uninstalled, you can reinstall it from the below location by simply double click on “Syncfusion Essential JS2 AspNet MVC VSExtensions” and click Install.    
    Example Location: C:\Program Files (x86)\Syncfusion\Essential Studio\ASP.NET MVC - EJ2\\Utilities\Extensions          
After performing all these steps and the same issue exists, kindly follow the steps suggested in the below KB article link and send us the zip file which consists of Syncfusion Installer logs generated by our tool.  It would be much helpful for us to check the reported issue and provide you the solution at the earliest.
