In the bundle file replace:
<BootstrapperApplicationRef Id="WixStandardBootstrapperApplication.RtfLicense" />
with:
<BootstrapperApplicationRef Id="WixStandardBootstrapperApplication.HyperlinkLicense"> <bal:WixStandardBootstrapperApplication xmlns:bal="http://schemas.microsoft.com/wix/BalExtension" LicenseUrl="" /> </BootstrapperApplicationRef>
WixStandardBootstrapperApplication has three variants as explained in the WiX Manual. HyperlinkLicense is the simplest. It has a license link on the welcome page instead of a license page. It allows you to specify an empty URL for the license, in which case it would not display the link.
