I need to set up a launch condition that prohibits install if a particular file
is NOT installed on the machine. What I have tried
(that did not work) was:
<Property Id="PATH32" >
<RegistrySearch Id="Path32" Root="HKLM" Key="<actual key covered by
NDA>" Name="Path" Type="raw" />
</Property>
<Property Id="PATH64" >
<RegistrySearch Id="Path64" Root="HKLM" Key="<actual key covered by
NDA>" Name="Path" Type="raw" />
</Property>
<Property Id="ADDIN" >
<DirectorySearch Id="AddinDir" Path="[PATH32]" >
<FileSearch Id="AddInFileSearch" Name="<actual file name covered by
NDA>" />
</DirectorySearch>
<DirectorySearch Id="AddinDir" Path="[PATH64]" >
<FileSearch Id="AddInFileSearch" Name="<actual file name covered by
NDA>" />
</DirectorySearch>
</Property>
<Condition Message="<message not relevant to the problem>"
><![CDATA[Installed OR ADDIN]]></Condition>
The reason for TWO directory/file search nodes is, the one installer package
must support installing on both 32 and
64 bit machines, and the registry key differs on the two platforms.
On a 32 bit machine it is
HKLM/SOFTWARE/<value covered by NDA>
and on a 64 bit machine it is
HKLM/SOFTWARE/Wow6432Node/<value covered by NDA>
(The two <value covered by NDA> are the same).
According to the Wix Docs, the Directory/File search nodes that do NOT find the
file should not pass a value
to the parent, giving me just the one that DID find the file.
Since my own test machine is a 64 bit machine, I commented out the 32 bit
directory search, and it STILL is not working.
Any suggestions on how I can make this work?
