Hi,
The Publisher field contains the value of the Manufacturer property. This property can be edited in AI in the "Product Details" page.
According to Microsoft documentation this property is required:

For this reason AI will not let you enter an empty value.
You could hack the MSI with Orca to obtain this result, although this is not recommended.
Go to the Property table and change the value of the Manufacturer property to " " (a string containing a space). You cannot leave the value empty since Windows Installer disallows this. Now the field will show blank.
If you delete the row the Publisher field will be removed completely from the Control Panel information. But, in this case, the validation of the MSI will fail, signaling the error: "The entry Manufacturer is required in the Property table".
Regards,
Mihai
