Is there any Patch for Age of Empires III

Hi friends. Today I installed Age of Empires III, Warlord and Asian Dynasty.

First
I played Age of Empires III (age3.exe), it ran smooth.
Then I installed Warlord (age3x.exe), it was running a little bit slow.
Then I installed Asian Dynasty(age3y.exe), it ran smooth.
When I tried to play Age III from Warlord (age3x.exe), it was running slow again.
When I tried to play Age III from Asian Dynasty(age3y.exe), it ran smooth.

So my problem is why is Warlord (age3x.exe) running slow.

Second
Is there any way to play Warlord from Asian Dynasty(age3y.exe).
