[WiX-users] Overwriting FileCost for Feature

[Adam K. <mig...@gm...>]

I have a Feature that, when selected, kicks off a Custom Action that goes
and downloads files from a network location to the local machine.  Because
these files aren't put down by the installer, they aren't taken into account
during the FileCost stage, so on the CustomizeDlg screen (provided with
WixUIExtension), the ItemSize is "wrong".  Is there a way to manually
overwrite the size that is calculated?  Or a way to hijack the SelectionSize
event that the SelectionTree publishes to show a different number?

Thanks,
Adam
