Answer 1

I think you need to set the Win64 property to Yes for one of the nodes.

Answer 2

Something like this would probably do the trick:

<MajorUpgrade AllowSameVersionUpgrades="yes"
          DowngradeErrorMessage="Can't downgrade."
          Schedule="afterInstallInitialize" />


<Property Id="APPLICATIONFOLDER" Secure="yes">
    <RegistrySearch Id="FindInstallLocation"
        Root="HKLM"
        Key="Software\Microsoft\Windows\CurrentVersion\Uninstall\[WIX_UPGRADE_DETECTED]"
        Name="InstallLocation"
        Type="raw"
        Win64="yes" />
</Property>


<CustomAction Id="Overwrite_WixSetDefaultPerMachineFolder" Property="WixPerMachineFolder" Value="[ProgramFiles64Folder][ApplicationFolderName]" Execute="immediate" />
<InstallUISequence>
    <Custom Action="Overwrite_WixSetDefaultPerMachineFolder" After="WixSetDefaultPerMachineFolder" />
</InstallUISequence>
<InstallExecuteSequence>
    <Custom Action="Overwrite_WixSetDefaultPerMachineFolder" After="WixSetDefaultPerMachineFolder" />
</InstallExecuteSequence>

<SetProperty Id="ARPINSTALLLOCATION" Value="[APPLICATIONFOLDER]" After="CostFinalize" />

UPDATE: SetDirectory schedules the action prior to WixSetDefaultPerMachineFolder - code updated for manually scheduled elements to schedule between WixSetDefaultPerMachineFolder and WixSetPerMachineFolder. Tested OK with OP sample code under Win7 x64

UPDATE2: Added action to set ARPINSTALLOCATION as http://robmensching.com/blog/posts/2011/1/14/ARPINSTALLLOCATION-and-how-to-set-it-with-the-WiX-toolset

Answer 3

I had to change two things to make WIX put my 64-bit app in the Program Files folder:

A. In the WIX Package element, add 'Platform="x64"':

‹Package Description="desc..." Manufacturer="company..." InstallerVersion="200" Platform="x64" Compressed="yes" /›

B. In the Directory element for the top folder, change ProgramFilesFolder to ProgramFiles64Folder:

‹Directory Id="ProgramFiles64Folder" Name="PFiles"›

(I also had to include the ‹program name› .exe.config file in the folder for the program to work correctly)
