Hi everyone,

at the moment I am trying to find out whether another product on which
our product depends is installed. Retrieving the path to the folder from
the registry works flawlessly so far. However, I can't manage to get
further than this.

First I retrieve the path from the registry (which works):

   <Property Id="PRODUCT_FOLDER">
     <RegistrySearch Id='SearchProductInstallDir' Type='raw' Root='HKLM'
                     Key='[KEYNAME]' Name='Services' />
   </Property>

PRODUCT_FOLDER now contains the path and I try to find out whether
[PRODUCT_FOLDER]\bin\file.exe exists. However, this doesn't seem to
work. In all cases PRODUCT_VALID is empty:

   <Property Id="PRODUCT_VALID" >
     <DirectorySearch Id="SearchProduct" Path="[PRODUCT_FOLDER]">
       <DirectorySearch Id="SearchProduct.bin" Path="bin">
         <FileSearch Name="file.exe" />
       </DirectorySearch>
     </DirectorySearch>
   </Property>

I also tried this, which didn't do any good either:

   <Property Id="PRODUCT_VALID" >
     <DirectorySearch Id="SearchProduct" Path="[PRODUCT_FOLDER]\bin">
       <FileSearch Name="file.exe" />
     </DirectorySearch>
   </Property>

Does anyone have any idea how to resolve this? Out of curiosity I tried
[WindowsFolder] instead of [PRODUCT_FOLDER] and it worked (file was
regedit.exe for testing).


Cheers,
