I have the following Property "MAINDIR" and it is populated correctly
from the registry....
<Property Id='MAINDIR'>
<RegistrySearch Id='AppInstallRegistrySearch' Type='raw'
Root='HKLM' Key='Software\OurSoftwareCompany\SoftwareName' Name='Install
Directory' />
</Property>
And then I have another property call "VDDIR" and I use the "MAINDIR"
property to help build the path for my virtual directory....however I
can see that instead of the path being built by replacing the MAINDIR
property with it's value it simply is leaving the path with "[MAINDIR]"
. Here are the properties as reported in the MSI log:
Property(S): MAINDIR = C:\PROGRA~1\SoftwareDir\
Property(S): VDDIR = [MAINDIR]webmain
<Property Id='VDDIR'>[MAINDIR]webmain</Property>
How do I use the value from one Property in another one? Any help would
be greatly appreciated. It appears that maybe it is defining the
property of VDDIR before it is getting the value of MAINDIR...if so how
can I ensure that MAINDIR is populated first. TIA.

Here is an excerpt from the WiX tutorial that shows how to do it, but I
can't seem to make it work. Anyone able to get this to work?
<Property Id="INSTALLDIR">
<IniFileSearch Id='AcmeFoobarIniFile' Type='directory'
Name='SampleRegistry.ini' Section='Sample' Key='InstallDir' />
</Property>
There might be cases when simply knowing the directory is not enough:
you have to look into the directory and make sure a given file exists
there. Depth = n can be used to instruct the installer to look n levels
deeper than the specified Path. Zero or a missing Depth attribute means
only to look in the specified folder, not below it. We use square
brackets in Path to tell the installer to use the value of the
INSTALLDIR property-bracketed names will be looked up and if found,
replaced with their actual value. If not found, the string will remain
unchanged.
<Property Id="FILEEXISTS">
<DirectorySearch Id="CheckFileDir" Path="[INSTALLDIR]" Depth="0">
<FileSearch Id="CheckFile" Name="Lookfor.txt" />
</DirectorySearch>
</Property>
