I found out when creating SSIS packages that I need to have this SSIS Service installed in order to schedule them from SQL Server Agent. So with that said I've been trying all over to figure out how to get this service installed without wiping my existing instance. I've been all over online and no one seems to have the same issues that I'm having or their resolutions aren't helping me out. Here's what I do so far and the wall that I'm hitting:
I go to Start/All Programs/Microsoft SQL Server 2008 R2/Configuration Tools/SQL Server Installation Center (64-bit)
When the console opens I click on Installation and then "New installation or add features to an existing installation"
I then get a pop up that says to "brows for SQL server 2008 R2 Installation media so I point it to my Desktop where the file "SQLManagementStudio_x64_ENU.exe" resides and I get an error that says that my desktop "is not a valid installation folder"
Please help me figure this out, I've been racking my brains for days! The only solutions I've found online for this error are to completely uninstall everything and re-install and that's just not an option.

I have looked at another link within stack overflow that "may" address my problem.
Add SSIS to existing SQL Server instance
It says that I have to get my hands on the "installation media folder" or download it from Microsoft's website. I can't however find anything on their website besides the "SQLManagementStudio_x64_ENU.exe" file that I was referring to later.

When I try to just use SQLManagementStudio_x64_ENU.exe I get to the point where I select my instance and get this 'instance id required but missing' error. Here's a screenshot
