this will help Based on my reading of the Wix Schema documentation, your problem is that you have the CopyFile element nested under a File element. Ditch the File element and just have the CopyFile sit under the Component:
code :

Share : facebook icon twitter icon

Any of those help The expression has to evaluate to true to allow installation. The "or Installed" is meant to prevent the lack of Access from interfering with a repair / uninstall.
code :
<Condition Message="Access not installed!">
  ACCESSRUNTIMECHECK ~= &quot;Access.Application.12&quot; Or Installed

fixed the issue. Will look into that further Use the Registry.GetValue() method:
code :
var myValue
  = Registry.GetValue(@"HKEY_CURRENT_USER\missing_key", "missing_value", "hi");

// myValue = null (because that's just what GetValue returns)
var myValue
  = Registry.GetValue(@"HKEY_CURRENT_USER\valid_key", "missing_value", null);

// myValue = null (because that's what you specified as the defaultValue)
    var myValue = Registry.GetValue( ... );  // throws exception on invalid keyName

    if (myValue != null)
        Registry.SetValue( ... );
catch (ArgumentException ex)
    // do something like tell user that path is invalid

wish helps you The WiX FileSearch, DirectorySearch, Condition, and CopyFile elements are what you are looking to use. Create a property, when executing the msi if the property is set then the DirectorySearch and FileSearch elements will look in the path for that property, setting another property (MYFILEEXISTS for example) then if MYFILEEXISTS CopyFile will run with the path.

like below fixes the issue It's not 100% confirmed in your question, but I would give strong odds that:
you are testing on a 64-bit installation of Windows, you are creating and visually verifying the registry key using C:\Windows\System32\Regedt32.exe or equivalent, and you aren't aware that the InstallScript engine runs as a 32-bit process, or aren't aware of the implications.
