WiX - How to set a property conditionally

Possible duplicate:
Wix - change the installation folder based on privileges

Well, this question arose when I tried to solve my problem in How to get different registry keys for all users and one user .

I am basically trying to do the following:

if ALLUSERS=1 then
   set InstallDir to Property1
else 
   set InstallDir to Property2

Does anyone know how to do this?

Ok, just finished. My wxs look like this:

<CustomAction Id="PerUserInstall"    Property="InstallDir" Value="[INSTALLDIR1]" Execute="immediate" />
<CustomAction Id="PerMachineInstall" Property="InstallDir" Value="[INSTALLDIR2]" Execute="immediate" /> 
<InstallExecuteSequence>
    <Custom Action="PerUserInstall"    After="AppSearch">ALLUSERS="" OR (ALLUSERS=2 AND (NOT Privileged))</Custom>      
    <Custom Action="PerMachineInstall" After="AppSearch">ALLUSERS=1  OR (ALLUSERS=2 AND Privileged)</Custom>
</InstallExecuteSequence>

Thanks to @shambulator for the link. Please note that I use After="AppSearch"instead Before="CostFinalize", because this will lead to the execution of the action immediately after searching the registry.
