So, you were attempting to install the Master Data Services Plugin for Excel, but couldn't get the install to actually process due to it saying the prerequisites are not installed:
You have made sure you have the right version (32 bit) to match the version of excel (2010), and have the full version of .net 4.5 installed. If you try to install the full version of .net 4.0, you are told that the newer (4.5) version already is installed.
