You can not downgrade Windows installer

<div>
Not interested in downgrading.<br />
<br />
I take it that this statement means Windows 7 and Server 2008 R2 come with WI 5.0?<br />
<br />
'Windows Installer 5.0 5.0.7600.16385 or greater Released with Windows Server 2008 R2 and Windows 7.'<br />
<br />
They only thing in those articles about querying the version of WI gives examples of calls. &nbsp;Is there any command that can be ran from the cli to determine the actual version of WI.
