TCNEAR RULE #1 Firstly install dektop konnekt 6 whenever you install windows.
Solution :
When you run x86×64TC_Audio_Interface_Software_241_6489_350.exe it will create a file named WIS874732AE6BB34BE18F6FA1DCEA32B836_2_4_1_6489.MSI in C:\Program Files\Common Files\Wise Installation Wizard (for 64 bit C:\Program Files (x86)\Common Files\Wise Installation Wizard).
Then open a command promt as administrator. For this browse to Start->All Programs-> Accessories and right click on Command Promt. Then select Run as administrator
Now type this cd c:\Program Files\Common Files\Wise Installation Wizard and press enter. (for 64 bit: C:\Program Files (x86)\Common Files\Wise Installation Wizard)
Type this WIS874732AE6BB34BE18F6FA1DCEA32B836_2_4_1_6489.MSI /qn /L* tcsetup.log and press enter.
It will install tc near and drivers on background. After few minutes restart the PC and then plug in Desktop Konnekt.
Now you can set your tc near as default sound card and hear the sound 
Below you can see my unsuccessfull steps before solve the problem:
This error occurs when i try to install driver of tc electronic desktop konnekt 6

NEVER DO THIS. Delete all files under c:\windows\installer. No success.
cd c:\windows\system32\drivers
del TCNear.sys
del TCNearAudio.sys
del TCNearMidi.sys
—-
cd c:\windows\system32
del TCNearAsio.dll
—
cd c:\Users\myuser\Recent
del tcn*
—-
Still no Success !
Finally i did a system restore.
And now i can run the installer.
But now there is another problem. I cand send audio to desktop konnekt 6. I run tcnear control panel but it says me ‘there is no sound card’.
So i have to do a system restore again 
Normally in this step, just uninstall the tcnear software, restart, then change your 1394 controller to “legacy”, restart, install tcnear software, restart. And now you can hear sound from dekstop konnekt 6. But i already tried more and more things
i have time.
I do another system restore.http://orhanturk.com.tr/admin/Pages/Add_entry.aspx
With first start i change the 1394 controller to legacy. In same time windows ask me to restart because it installed something without asking me.
When the machine is restarted i install the newer version of tcnear (241) . Software restarts the computer when finish installing.
After restart i can hear something from my desktop konnekt 6.
I really really missed this. No i can run ableton live and make some music.
PS: You wonder about how did i come to this point ? I uninstalled tcnear and reinstalled again. But i didnt hear sound from konnekt. So i searched for near,tcnear,konnekt,electronic etc. in registry and file system. Deleted everything what i found. PLEASE YOU DONT MAKE THESE MISTAKES. Just do a system restore.
