I can't seem to call this executable correctly in my psake deploy script.

If I do this:

exec { "$ArchiverOutputDir\NServiceBus.Host.exe /install" }

It simply outputs this (and is clearly not calling the executable - just outputting the value of that expression):

c:\ReloDotNet2_ServiceEndpoints\Archiver\NServiceBus.Host.exe /install

But if I do this:

exec { c:\ReloDotNet2_ServiceEndpoints\Archiver\NServiceBus.Host.exe /install }

I get the expected output from the executable.

How do I correctly call an executable with a variable in the path to the executable in psake? If this is actually a PowerShell issue, please feel free to correct the question to reflect that insight.
