<Property Id="SEARCHFOROPENOFFICE" Value="absd">
<RegistrySearch Id="OpenOfficeSearch"
Key="Software\OpenOffice.org\UNO\InstallPath" Name="OpenOffice.org 2.3"
Root="HKLM" Type="raw">
</RegistrySearch>
</Property>
<Condition Message="installation can't proceed as you don't have open office
installed on your machine.Please install OpenOffice, version 2.3 From
http://download.openoffice.org";>Not SEARCHFOROPENOFFICE="absd"</Condition>
