Where to find dbgsrv to use with IDA

Hi everyone,
I'm using IDA to disassemble a 64-bit application. So before debuging I need to select the debugger but no matter what, it tells me:

"Please run the 64-bit debugger server (dbgsrv.exe) to debug 64-bit applications." and then it asks me to locate the dbgsrv.exe but I can't find it.

I have installed the Microsoft visual studio 8, 9 and 11 plus SDK but there is no such a thing as dbgsrv.exe
Does anyone know where I can find/download this exe file? or is there any other way to use IDA Pro for a 64x application and not have the dbgsrv.exe?

Thank you so much

found it ... I should've installed the windows driver kit
but now the problem is that IDA says "the file can't be loaded by the debugger plugin. please verify that the parameters are valid" and then it asks for the parameters ... :(

The parameters are:
"-t tcp:port=4000,server=localhost" or "tcp:port=4000,server=localhost"
but it says:

Windbg: using debugging tools from '<PATH>'
Connecting to debugger server with '-t tcp:port=4000,server=localhost'
Connect failed: The server is currently disabled.

so I tried to enable it by using the cmd and typing:

dbgsrv -t tcp:port=5000,server=localhost

but then a window pops up and says:
Error 0x80972740
StartProcessServer

PS: interesting observation! the smilie faces are : p with no space between indeed :))

I edited your post and selected the -> "Disable smilies in text" options;)

I hope some one help you because I sure can not.
