Sure, isn't too hard.
1) use notepad or some text editor and paste this

Quote:

<?xml version='1.0' encoding='Windows-1252'?> <SimBase.Document Type='Launch' version='1,0'> <Descr>Launch</Descr> <Filename>exe.xml</Filename> <Disabled>False</Disabled> <Launch.ManualLoad>False</Launch.ManualLoad> <Launch.Addon>  <Name>Couatl</Name>  <Disabled>False</Disabled>  <ManualLoad>False</ManualLoad>  <Path>fsdreamteam\couatl\couatl.exe</Path> </Launch.Addon> <Launch.Addon>  <Name>EZdok camera addon</Name>  <Disabled>False</Disabled>  <Path>C:\Program Files (x86)\EZCA\EZCA.exe</Path> </Launch.Addon> </SimBase.Document>

2) save the file as .xml (not .xml.txt) in C:\Users\Berlopez\AppData\Roaming\Microsoft\FSX
3) done!  :D
My entries above are examples, but I'm sure you get the structure.
There's also a chance that the addons which rely on that file create a new one when you reinstall them. Take the FSDT addon manager for example.
