[wix-users] custom bootstrapper - customize UI .NET prerequisite installation

[Tobias S]

No. Just overwrite the PreqbaThemeXml + PreqbaThemeWxl:

  <WixVariable Id="PreqbaThemeXml"
Value="$(var.OutDir)..\Prerequisites\mbapreq.xml" Overridable="yes" />
  <WixVariable Id="PreqbaThemeWxl"
Value="$(var.OutDir)..\Prerequisites\mbapreq.wxl" Overridable="yes" />

Think PreqbaThemeXml should be enough for dialog modifications. Also not
sure about the file endings as they once were xml and seem now thm for the
PreqbaThemeXml.
