Installing SDK for Missions

It's been almost 2 years since I have installed the FSX SDK for creating missions. For some reason it is not working. I think part of it has to do with the path since I have a Windows 64 bit but I am also confused about the other items to be installed. I am reading the FS Developer wiki but it's not sinking in for seom reason. I have done this before and it took me awhile that time too.

Any help appreciated. Do I have to install additional files from Microsoft?

Here is the developer link I am reading but I am not understanding this go around about the other files to install!

And here is the info for the path to the tool!

<?xml version="1.0" encoding="Windows-1252"?>

<SimBase.Document Type="Launch" version="1,0">

<Descr>Launch</Descr>

<Filename>dll.xml</Filename>

<Disabled>False</Disabled>

<ManualLoad>False</ManualLoad>

<Launch.Addon>

<Name>Object Placement Tool </Name>

<Disabled>False</Disabled>

<Path>..\Microsoft Flight Simulator X SDK\SDK\Mission Creation Kit\Object_Placement.dll</Path>

</Launch.Addon>

</SimBase.Document>

My FSX files are in \Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X SDK\SDK\Mission Creation Kit\Object_Placement.dll

I have tried entering that path and nothing works.

Any ideas? Shouldn't I see the Tools menu if it works correctly when I go to Free Flight?
