Does anyone have the inside track on getting wceload to run absolutely
silently during updates (installing a CAB file after the application
has already been installed at least once)?

I've heard all of the suggestions re: using wceload /noui /noaskdest /
silent which work fine for the initial install, but updates still
cause wceload to post a MessageBox saying:

"The previous version of <providerName appName>
will be removed before the new one is installed.
Select OK to continue or Cancel to quit."

If a desktop installer is executing wceload over RAPI, any dialog is a
deal killer.

Some posts suggest:
Setting "HKLM\Software\Apps\<providerName appName>\Instl" to 0
Deleting "HKLM\Software\Apps\<providerName appName>"
completely, but I've tried both and concluded that something more is
required.

I've seen posts suggesting that the following keys should all be 0:
HKLM\Software\Apps\Microsoft Application Installer\fEnableCef
HKLM\Software\Apps\Microsoft Application Installer
\nDynamicDelete
HKLM\Software\Apps\Microsoft Application Installer\fAskDest
HKLM\Software\Apps\Microsoft Application Installer\fAskOptions
Maybe that helps, but it's also insufficient.

Other posts suggest using the CE_COPYFLG_NODATECHECK on each of the
copyFile lines in the INF file, but that's still insufficient.

So... I'm hoping a Mobile MVP or other serious player will know the
magic ingredient. I look forward to any suggestions.

I forgot to mention that the CAB is signed and the executable within
is also signed. Either not being signed will cause wceload to post a
warning dialog.

I look forward to any suggestions...
