What Alex means is you can set the ARPINSTALLLOCATION property (http://msdn.microsoft.com/en-us/library/aa367589.aspx) to do that for you using a type 51 custom action. The following code should work for you Thomas:
<CustomAction Id="SetARPInstallLoc" Property="ARPINSTALLLOCATION" Value="[INSTALLDIR]" /> <InstallExecuteSequence> <Custom Action="SetARPInstallLoc" Before="RegisterProduct" /> </InstallExecuteSequence> That will (should) set the "InstallLocation" value under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{ YOUR-PRODUCT-GUID} Good Luck.
