Reason:
The main reason for this exception is due to multiple bindings enabled for the the IIS website under which BizTalk360 is installed. You can check this easily by seeing the right hand side pane as shown below:

There are couple of ways we can sort this issue:
Solution #1:
If ASP.NET 4.0 is installed on the server, you can change the BizTalk360 IIS Application pool to use ASP.NET 4.0 as shown in the below picture:

And you can add the following line to the Web.Config file

Solution #2:
If in case you don't have ASP.NET 4.0 running in the server, then your second option is to create a dedicated website for BizTalk360 with a custom port number (ex: 90) and install BizTalk360 in the dedicated website instead of the default website.

You must create the website manually before starting the BizTalk360 installer. The installer will display the options in the drop down box to choose the website.
