Hello I am really new to WiX. I have a application that i need to Also install the drivers (.inf, .cat, .sys) for along with desktop icons start menu shortcuts and so forth. I have tried implementing the different codes That have to do with such from SO but am not having much luck I have also tried KK's blog and tried following his example.

You will want to use the Difx extension, which you can access by adding xmlns:difx="http://schemas.microsoft.com/wix/DifxAppExtension" to the Wix tag. You will also need to add a reference to either difxapp_x86.wixlib or difxapp_x64.wixlib to your project.

You'll need to reference it like this:

<Feature Id="MyDrivers" Title="My Drivers">
   <Component Id="Drivers" Directory="DriverDir" Guid="*">
      <File Id="MyDriver.cat" Source="$(var.DriverFilesDir)\Driver\MyDriver.cat" />
      <File Id="MyDriver.inf" Source="$(var.DriverFilesDir)\Driver\MyDriver.inf" />
      <File Id="MyDriver.sys" Source="$(var.DriverFilesDir)\Driver\MyDriver.sys" KeyPath="yes" />
      <File Id="WdfCoinstaller01011.dll" Source="$(var.DriverFilesDir)\Driver\WdfCoinstaller01011.dll" />
      <difx:Driver AddRemovePrograms="no" Legacy="no" PlugAndPlayPrompt="no" Sequence='1' />
   </Component>
</Feature>

Note the <difx:Driver> tag recognizes your driver components above it, so order does matter. More information here.

You will need to change the directory of the Component tag to match something in your directory structure or you could add <Directory Id="DriverFiles" Name="Drivers" /> under your ApplicationProgramsFolder.

The Source value in the File tags uses the preprocessor variable DriverFilesDir, which you can either replace with a hard coded path, or you can set it in your project settings. Under the Build tab, to "Define preprocessor variables:", you would add something like DriverFilesDir=..\Drivers. Note multiple variables are separated by semicolons.
