title: WIX and preconditions (DLLs/OCXs in System32, ...)
body: <p><em>What i have:</em><br/>
  I have an installations routine written in WIX 3.6 (with heat, candle, light)
  <br/><br/>
  <em>What's the problem:</em><br/>
  it only installs the app-folder-files (registering activex-components, registering and starting a service, making regentries, ...) and not DLLs/OCXs in the System32-folder. also the avalabiliy of ADO (ActiveX Data Objects) isn't checked.
  <br/><br/>
  Which is the best way to deal this?</p>
