I'm learning WiX and have been experimenting with a 64-bit install
package for Vista64 During the install, I would like to run a 64-bit
configuration tool. I can successfully launch the tool with a normal
MSI custom action.
However, when I try to launch the 64-bit exe silently using the WixCA
CAQuietExec, it doesn't work. From the log files, it looks like the
32-bit custom action server is started and it fails to execute the
64-bit exe. Which makes sense, I don't think a WOW 32-bit process can
launch a 64-bit exe. I'm thinking I need a 64-bit version of WixCA
CAQuietExec. Does this exist? Are there other options?
A 32-bit process can launch a 64-bit process but a 32-bit process sees a
"virtualized" file system so it can't find the 64-bit file in its view
(System32 -v- SysWOW64, in this case).
There isn't currently a 64-bit build of the WiX custom actions as we
haven't needed them. This is another instance where we either need
64-bit CAs or to code the 32-bit CAs to support being run with 64-bit
data. Please enter a feature request so we can track the need. There's
no workaround I can think of.
