How to get directory by DirectorySearch?

[MasterBran]

For some reason, I need to install some file to the XLSTART folder under the Excel's path, first I get the file path by this code
<Property Id="OFFICEPATH"> <RegistrySearch Id="OFFICE" Type="file" Root="HKLM" Key="SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\excel.exe" Name="InstallDir" /> </Property>
and then, I use 'DirectorySearch' to get the folder path of excel.exe(Something wrong here).
<Property Id="OFFICEDIR"> <DirectorySearch Id="EXCELDIR" Path="[OFFICEPATH]" Depth="0" AssignToProperty="yes"> <FileSearch Id="EXCELXE" Name="excel.exe" /> </DirectorySearch> </Property> <SetDirectory Id="OFFICETARGETDIR" Value="[OFFICEDIR]" />
Finally, I specify the target path like this
<Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="OFFICETARGETDIR"> <Directory Id="INSTALLFOLDER" Name="XLSTART" /> </Directory> </Directory>
but it's not worked, all of my file installed in F:\XLSTART. How could I do this?

That's good news, @MasterBran. Could you maybe post your solution here and mark it as the answer so if others with similar issues find this thread in the future they'll know what you did to solve it?

Thanks for replay, when I realized that was very easy problem, I thought most people might not need it,so...
Anyway, I post my solution and marked as answer.

Maybe that is actually a very simple but possibly overlooked problem, the bug occur in <Property Id="OFFICEPATH"> <RegistrySearch Id="OFFICE" Type="file" Root="HKLM" Key="SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\excel.exe" Name="InstallDir" /> </Property>,the attribute Name of RegistrySearch is wrong, that must same to the registry item name(In my case,there should have no attribute Name), and then I could get the folder path of excel.exe. The DirectorySearch is needless, so this is my final code
<Property Id="OFFICEPATH"> <RegistrySearch Id="OFFICE" Type="file" Root="HKLM" Key="SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\excel.exe" Name="InstallDir" /> </Property> <SetDirectory Id="OFFICETARGETDIR" Value="[OFFICEDIR]" /> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="OFFICETARGETDIR"> <Directory Id="INSTALLFOLDER" Name="XLSTART" /> </Directory> </Directory>
