[WiX-users] using dism.exe in my custom action

[Lian Jiang]

Hi,

I am trying to use dism.exe in one of my custom actions for Windows server 2008 
R2.

There are two dism.exe, one in c:\windows\system, the other in 
c:\windows\syswow64. No matter which one I use, running msi fails with this 
error:

You cannot service a running 64-bit operating system with a 32-bit version of 
DISM. Please use the version of DISM that corresponds to your computer's 
architecture.

Here is my custom action:
<!-- install .NET framework -->
    <CustomAction Id="InstallNetFramework"
                  Property="InstallNetFrameworkDeferred"
                  Value='"[WindowsFolder]SysWOW64\dism.exe" /online 
/enable-feature /featurename:NetFx3'
                  Execute='immediate'
                  Return='check'/>
    <CustomAction Id="InstallNetFrameworkDeferred"
                  BinaryKey='WixCA'
                  DllEntry="CAQuietExec"
                  Execute="deferred"
                  Return="check"
                  Impersonate="no" />

Did I miss anything?


Thanks
Lian
