the 1.27a patcher dont work for me

[Mr. Gameplay Knowledge]

I installed on my new PC warcraft 3 roc and tft.
So i try to patch it,and it didnt work for me.
Can someone help me with this:

-Added:
Here is what is written under the error's:
The system cannot find the path(C:\Program Files (x86)\Warcraft III).
And btw. the path is in the PC,but the patcher cant find it.

start the patcher as administrator

You should check the Registry too.

You may wanna take a look here.
