WixUIExtension.dll could not load from the network path while creating MSI package using WIX


I am using WIX (Windows Installer XML 3.7) to create an MSI package.

This is in my *.WIXPROJ file

    <WixExtension Include="WixUIExtension">



When creating MSI file from network path following error is occurred.

The extension '\BuildFolder\wix37-binaries\WixUIExtension.dll' could not be loaded because of the following reason: Could not load file or assembly 'file://\BuildFolder\wix37-binaries\WixUIExtension.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

Please help me how to resolve this issue.

Regards, Dileep
