[Setup]: AllowUNCPath

Valid values:

Default value:

yes
Description:

If set to no, the user will not be allowed to enter a UNC path (such as "\\server\share") on the Select Destination Location page of the wizard. This was the default behavior in Inno Setup 2.0.17 and earlier.

To fully disallow installation to network locations, you must also set AllowNetworkDrive to no.
