Running 32bit Applications with 64bit IISNode

When you enable 32 bit applications in x64 version of IIS 7.x, the IIS worker process will be created in WOW mode. This mode requires that iisnode is installed on the machine in WOW mode as well. This can be accomplished by downloading the x64 bit iisnode MSI and installing it with the WOW=1 option as follows:

msiexec /i iisnode-full-iis7-v0.1.17-x64.msi WOW=1
