The reason you see the AdvancedWelcomeEulaDlg a second time is because in
AdvancedWelcomeEulaDlg.wxs there is the following:
<InstallUISequence>
<Show Dialog="AdvancedWelcomeEulaDlg" Before="ProgressDlg">NOT
Installed</Show>
</InstallUISequence>
Hence it's showing up in the InstallUISequence.
What happens when you click Next on the WelcomeDlg is it does what you've set
the Next button to do. By default in WixUI_Advanced.wxs it spawns
VerifyReadyDlg using the NewDialog function when Next is clicked. You must have
also modified that too if you're getting to the FeaturesDlg somehow (I'm
assuming you've made it spawn AdvancedWelcomeEulaDlg).
The only way to fix it is to copy & paste the contents of
AdvancedWelcomeEulaDlg.wxs from the WiX source into your code, rename the
Dialog to something unique (e.g. MyAdvancedWelcomeEulaDlg), remove the above
code to stop it showing twice then update the references to point at your new
custom version & remove the references to the original. You'd also want to
change your <Show Dialog="WelcomeDlg" Before="AdvancedWelcomeEulaDlg">1</Show>
to <Show Dialog="WelcomeDlg" Before="ProgressDlg">1</Show> otherwise it will
probably give you problems building or running as it'll be trying to place a
dialog before a dialog which doesn't exist.

Subject: [WiX-users] another noob question about customizing the standarddialog
sets
I'm trying to customize the WixUI_Advanced dialog set, and had something
fairly simple, but it doesn't seem to work the way I expected. I'd like the
Welcome dialog to show up always (not just when doing a patch), so I copied
the WixUI_Advanced.wxs internals and changed the InstallSequence at the end
to say
<Show Dialog="WelcomeDlg" Before="AdvancedWelcomeEulaDlg"
>1</Show>
(the condition used to be 'Installed AND PATCH'.
Now, if I run an initial install, things look okay until I get to the end of
the Feature dialog, at which point the AdvancedEulaDlg shows up. Looking at
the MSI in Orca, I see
the following:
Action Condition Sequence
WelcomeDlg 1 1295
AdvancedWelcomeEulaDlg NOT Installed 1296
MaintenanceWelcomeDlg Installed AND NOT RESUME AND NOT Preselected AND
NOT PATCH 1297
ResumeDlg Installed AND (RESUME OR Preselected)
ProgressDlg
ExecuteAction
The conditions for AdvancedWelcomeEulaDlg and the others are baked into
their .wxs files in UIExtension. I assume what was intended is that during
InstallUISequence, each will be evaluated as an initial condition and that
particular dialog will show up (and none of the others will later evaluate
to true), and then Next and Back definitions will dictate what happens
next. That's reasonable. However, it appears I'm then unable to dictate my
own initial dialog (WelcomeDlg always, in our case). Is there some way to
remove the 'InstallSequence' items for the other dialogs without actually
copying and modifying the dialog .wxs source files? I couldn't find one,
but would love a pointer to something that explains how to do it.
Thanks!
Dave
