Google Picasa is a photo album and editing tool. Download it from http://picasa.google.com/. When new versions are released they're available from picasa.google.com (where the filename is picasa<version>-setup.exe) before they are from the likes of picasa.google.co.uk (where the filename is picasaweb-current-setup.exe).

Picasa is not that easy to silently install. Mainly because it forks processes after installation which have to be terminated. Therefore you need the Microsoft Taskkill command installed for it to work.

Picasa 3

Picasa 3 by default installs to %PROGRAMFILES%\Google\Picasa3.

Silently installing Picasa 3 when Picasa 2 is installed will automatically remove Picasa 2.

Picasa 3 doesn't include the Picasa Media Detector included with earlier versions.

Note that Picasa uninstall will open a web browser to ask for feedback.

Auto Update

Picasa's auto update feature defaults to 'update automatically'. For administrators or Power Users, when they first run Picasa it auto updates without prompting, even before you've managed to run it for the first time. For Limited user accounts, this setting causes it to prompt the user, asking if they want to update.

The automatic update feature can be turned off in various ways:

GUI (Per-user)

Tools → Options → General → Automatic Updates → Don't check for updates

Registry (Per-user)

(Note this registry key may now be wrong)

HKEY_CURRENT_USER\Software\Google\Picasa\Picasa2\Preferences\AutoUpgradeCheck=dword:00000000
HKEY_CURRENT_USER\Software\Google\Picasa\Picasa2\Preferences\AutoUpgradeAsk=dword:00000000

Google Updater Service (system-wide)

Either:

Change the Startup Mode of the Google Updater service:

sc config gusvc start= disabled

Uninstall the Google Updater service:

"%PROGRAMFILES%\Google\Common\Google Updater\GoogleUpdaterService" /UnregServer

Picasa 2

Picasa 2 installs to %PROGRAMFILES%\Picasa2. Changing this with installer options causes Picasa to install into repetitive %PROGRAMFILES%\Picasa2\Picasa2\Picasa2\... directories.

Use the following to perform a silent installation of Picasa 2.x:

<?xml version="1.0" encoding="utf-8" ?>
<packages>

<package id='Picasa' name='Picasa' revision='2' priority='3' reboot='false' >
  <check type='uninstall' condition='exists' path='Picasa 2' />

  <install cmd='"%SOFTWARE%\Picasa\picasa2-setup.exe" /S' >

  <install cmd='cmd /C taskkill /F /IM Picasa2.exe' >
    <exit code='1' />
    <exit code='128' />
  </install>

  <install cmd='cmd /C taskkill /F /IM PicasaMediaDetector.exe' >
    <exit code='1' />
    <exit code='128' />
  </install>

  <upgrade cmd='"%SOFTWARE%\Picasa\picasa2-setup.exe" /S' />

  <upgrade cmd='cmd /C taskkill /F /IM Picasa2.exe' >
    <exit code='1' />
    <exit code='128' />
  </upgrade>

  <upgrade cmd='cmd /C taskkill /F /IM PicasaMediaDetector.exe' >
    <exit code='1' />
    <exit code='128' />
  </upgrade>

  <remove cmd="%PROGRAMFILES%\picasa2\Uninstall.exe /S"/>
</package>

</packages>

The uninstall option may need testing.
