Wix .NET Custom Action running in 64 bit context

I've created a Wix (3.0) custom action written in .NET. Fine.

The problem is that I shall access to the Windows registry during the execution of the custom action, but I have a redirection on the Wow6432Node...

Looking for something useful in the log file of the MSI installation, I foun开发者_运维技巧d the following log lines:

Hello, I'm your 32bit Impersonated custom action server.

SFXCA: Extracting custom action to temporary directory: C:\Windows\Installer\MSIB858.tmp-\

SFXCA: Binding to CLR version v2.0.50727

Calling custom action DemoLicenceCA!DemoLicenceCA.CustomActions.InstallDemoLicences

Of course, if the nice custom action server would run at 64 bit I could avoid this boring problem of registry rediction.

How is it possible to workaround this limitation?

The MSI package is built for 64 bit platform. The custom action DLL is build for any platform (CLI), and the MSI package is installing on Windows 7 64 bit.

Well, it is sufficient to force the build platform to x86 or x64 to run in the right context. That's a pity, since I have to manage two configuration instead of a single one, but this is not a big problem.
