NSClient++ Help (#1) - Version not supported on Win32bit - Installing 0.3.9-Win32.msi (#936) - Message List

I keep getting the above error message complaining that I'm trying to install a 64bit app into a 32bit O/S and it tells me to get the win32 version instead ..

I'm installing into win2k8 standard. This is the first server I've seen this error on.

Thoughts?
