[OTR-users] silent / unattended upgrade of 3.2.0 to 3.2.1 / 4.0

[Pete Boyd]

Hi. I'd like to roll out an upgrade from Pidgin OTR 3.2.0-1 to 3.2.1-2
to fix the security flaw across various computers running Windows XP.

I use WPKG to automatically deploy software to workstations and have
used 'pidgin-otr-3.2.0-1.exe /S' to initially silently install 3.2.0.

Running 'pidgin-otr-3.2.1-1.exe /S' gives dialogs saying 'pidgin-otr was
already found on your system and will first be uninstalled' and 'Are you
sure you want to completely remove pidgin-otr 3.2.0-1 and all of its
components?'.

If I instead do an uninstall of 3.2.0-1 first, using
'pidgin-otr-uninst.exe /S', then I still get 'Are you sure you want to
completely remove pidgin-otr 3.2.0-1 and all of its components?'.

I've tried upgrading to 4.0.0-1 instead, using 'pidgin-otr-4.0.0-1.exe
/S', and it also isn't silent, but at least just gives the one dialog
'Are you sure you want to completely remove pidgin-otr 3.2.0-1 and all
of its components?'

How do I perform a silent uninstall or upgrade please? Preferably to
3.2.1, but alternatively to 4.0?
Thanks
