title: qt isn't detected by qtcreator
body: <p>I'm triing to get a simple application to work on symbian (Nokia N97)
  I installed qt 4.7.4 and qtcreator 2.3.1 on my pc
  I installed qt 4.7.4 and CODA 4.0.23 on N97</p>
  
  <p>when i run the application from qtcreator i get the error:</p>
  
  <pre><code>Executable file: 9124 2011-10-23T16:37:36 C:\QtSDK\Symbian\SDKs\Symbian1Qt473\\epoc32\release\gcce\udeb\untitled.exe

  Finished. 
  </code></pre>
  
  <p>when i check the device info in qtcreator: projects > symbian devide > run > Device (info)</p>
  
  <pre><code>Qt version: Not installed on device
  ROM version:v 30.0.004 16-06-11 RM-555 (c) Nokia

  </code></pre>
  
  <p>the qt version isn't installed
  i did install the qt.sis in my qt sdk folder:</p>
  
  <pre><code>"C:\QtSDK\Symbian\sis\Symbian^3\Qt\4.7.4\qt.sisx"
  </code></pre>
  
  <p>What am I doing wrong?</p>
  
  <p>--------------EDIT--------------
  i tried installing qt for symbian^1:</p>
  
  <pre><code>"C:\QtSDK\Symbian\sis\Symbian^1\Qt\4.7.3\qt.sis"
  "C:\QtSDK\Symbian\sis\Symbian^1\Qt\4.7.3\qmlviewer.sis"
  "C:\QtSDK\Symbian\sis\Symbian^1\Qt\4.7.3\qtwebkit.sis"
  "C:\QtSDK\Symbian\sis\Symbian^1\QtMobility\1.1.3\qtmobility.sis"
  </code></pre>
  
  <p>the last 2 give the error: </p>
  
  <pre><code>update failed (no device)
  
  something went wrong
  An error occurred on installation of the file- Foutcode: 2153775107- (in ovi suite)
  </code></pre>
  
  <p>I probably need to use CODA, cause trk isn't supported in qt creator 2.3
  so i install:</p>
  
  <pre><code>"C:\QtSDK\Symbian\sis\Symbian^3\CODA\public_coda_installer_1-0-5_build2_signed.sis"
  </code></pre>
  
  <p>then i try to run the application from qt creator:
  error:</p>
  
  <pre><code>Launch failed: Command answer [command error], 1 values(s) to request: 'C|8|Processes|start|""|"test1.exe"|[""]|[]|true'
