Hi Jeremy!
I solved it this way:
Firstly I define a custom action for 32bit setup routine:
<?if $(var.ProcessorArchitecture)=x86 ?>
<CustomAction Id="CA_Err32BitMsiOn64BitOS" Error="The 32-bit version of
this product cannot be installed on a 64-bit version of Microsoft Windows."
/>
<?endif ?>
Secondly I call the custom action in the 32bit setup routine whenever it is
called on a 64bit machine:
<InstallExecuteSequence>
<?if $(var.ProcessorArchitecture)=x86 ?>
<Custom Action="CA_Err32BitMsiOn64BitOS" After="LaunchConditions">
<![CDATA[MsiAMD64 OR Intel64]]>
</Custom>
<?endif ?>
...
</InstallExecuteSequence>
<InstallUISequence>
<!-- Only schedule this custom action for the 32-bit MSI.
-->
<?if $(var.ProcessorArchitecture)=x86 ?>
<Custom Action="CA_Err32BitMsiOn64BitOS" After="LaunchConditions">
<![CDATA[MsiAMD64 OR Intel64]]>
</Custom>
<?endif ?>
...
</InstallUISequence>
To be honest I did not invent this by myself. I found this solution in a
blog. Unfortunately I cannot remember the URL of the blog any more.
Hope this helps.
Kind regards,
Rainer.

Betreff: [WiX-users] Prevent 32 bit MSI install on 64 bit OS
Before I resort to a CA that tries to call IsWow64Process(), is there
any other simple way to bail out if attempting to run a 32 bit installer
on a Win64 OS? (My product requires the 64 bit installer on a 64 bit OS)
Thanks,
Jeremy
