QuietExecute x86/x64

[chrpai]

I have a wix3 x86 MSI that uses QuietExecute to call SchTasks.exe. It was using the [SystemFolder] as part of the path.

I converted this project to wix v4 and built it as 64bit. Everything still "works" but it's still calling the 32bit SchTasks.exe and now references Wix4UtilCA_X86.

If I wanted to author something like this and have it automatically call the x86 or the x64 EXE depending on how I compiled, what would should that look like?
