CRM 4.0: E-mail Router download

I was doing a complete test upgrade this week and it was successful. As you are aware, you can not upgrade the CRM 3.0 E-mail router, but instead have to uninstall the previous version before installing the 4.0.

After uninstalling the CRM 3.0 E-mail router, I tried to follow the instructions to install the CRM 4.0 router. I looked for the files in the "Exchange" folder like the asked, but could not find this "Exchange" folder. I could not locate the files to begin the install!

I searched Microsoft's download site and found this link to download the E-mail router separately. Still not sure why it wouldn’t be included where it should be, but if you can't find it, here is the link.
