Unfortunately with MSI's AppSearch action, you don't have any real control over the order of the attempted resolution of each of the various properties.

But it seems that when the FILEEXIST condition is evaluated the INSTALLDIR is set to whatever was found in the registry, which means if the registry entry was not found, at this point the INSTALLDIR will be empty and it won't be, as I expected, the nested Directory tags we specified. [code] <!-- Check if in the registry we have already saved the path where the app should be installed --> <Property Id="INSTALLLOCATION"> <RegistrySearch Id="MyPathsFromRegistry" Type="raw" Root="HKLM" Key="Software\MySetup" Name="InstallDir"/> </Property> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder"> <Directory Id="MyFirstSetup" Name="MyFirstSetup"> <Directory Id="INSTALLLOCATION" Name="MyFirstSetup1.0"> <Component Id="MyExe" Guid="9660051E-43CA-4459-AEF1-290BBE3DE544"> <File Id="MyMainExe" Name="MyApp.exe" Source="..\MyApp\Debug\MyApp.exe" DiskId="1" KeyPath="yes"/> </Component> <Component Id="MyDocumentation" Guid="5D64FD41-B8FF-4B77-8777-4CFD81855A0B"> <File Id="MyDocu" Name="readme.txt" Source="..\MyApp\Debug\readme.txt" DiskId="1" KeyPath="yes"/> </Component> </Directory> </Directory> </Directory> </Directory> <!-- check if in the installation directory (egal if it's the one gathered from registry or the default one) has a lookfor.txt file and if not don't install the documentationc --> <!-- !!! ACTUALLY !!! for some reason, when the following Property is evaluated the INSTALLLOCATION is set to whatever was in the registry, and if no key was found in the registry this value is empty, so it was not yet set to whatever default directory path was specified with the nested Directory tags--> <Property Id='FILEEXISTS'> <DirectorySearch Id='DirSearch' Path='[INSTALLLOCATION]' Depth='0'> <FileSearch Id='FileSearch' Name='lookfor.txt'/> </DirectorySearch> </Property> <Feature Id="CompleteExe" Level="1"> <ComponentRef Id="MyExe" /> </Feature> <!-- install this feature only if you find the lookfor.txt file (Level 0 means the feature won't be installed) --> <Feature Id="CompleteDoc" Level="1"> <ComponentRef Id="MyDocumentation" /> <Condition Level="0"> NOT FILEEXISTS </Condition> </Feature> [/code] How can I do so that the FileSearch is done in INSTALLLOCATION whereas the INSTALLLOCATION is either the registry entry if found or the nested directory tag if registry entry was not found?
