Microsoft Office Visio Viewer 2007 with SP2
From WPKG | Open Source Software Deployment and Distribution
This is the silent installer for Microsoft Office 2007 Visio Viewer. As it's name says - it allows to view Microsoft Visio's files without having full Version of Visio installed. First you need to download setup file from: Microsoft's download page (link here - click). You'll find a .exe file which needs to be unpacked using some unzip application (eg. great 7zip or any other), you'll find five files inside:
vviewer.cab files12.cat vviewer.msi EULA eula.txt
Put them to some available location, in my case it is %SOFTWARE%\Microsoft\visioviewer\, of course you can use other, just remember to edit package command path. It should look somehow like that:
<package id="visioviewer" name="Microsoft Office Visio Viewer 2007" revision="1" reboot="false" priority="10">
<check type="uninstall" condition="exists" path="Microsoft Office Visio Viewer 2007" />
<install cmd='cmd /c msiexec /qn /i "%SOFTWARE%\Microsoft\visioviewer\vviewer.msi" ACCEPTEULA=1 ASSOCIATE=1 RESTART=0' />
<upgrade cmd='cmd /c msiexec /qn /i "%SOFTWARE%\Microsoft\visioviewer\vviewer.msi" ACCEPTEULA=1 ASSOCIATE=1 RESTART=0' />
<remove cmd='cmd /c msiexec /q /x{95120000-0052-0415-0000-0000000FF1CE}' />
</package>
And don't forget to add a line to your profiles.xml. Priority should not be important here since package doesn't have any dependencies.
