So I've searched all over the internet and always end up back at your boards and finally decided I'd register and share my exploits with windows 7 and eMGR

While I didn't recieve an error like the image you've posted (I am using Win7 RC build 7100) I have had some success with extracting the install files, running in compatibility mode install, I've used XPSP2&3 and Windows Server 2003 and both seem to work equally. However...

It will install the daylight savings patch just fine, then however when trying to install the C++ Redist I get an error, I'll post an image of that soon.

I'm thinking there has to be a workaround if we can all just put our heads together, because currently I'm eating up an extra XP license for the sake of a virtual machine with its soul purpose to run eManager for our company's phones.
