I looked up in the Intel Evaluation Center.
Unfortunately for the Intel Parallel Composer 2011 the default download is the 'Initial Release', not Update 6. You need to choose 'Update 6' from the 'Update (Build #) drop-down box in the download area and then select a download file.
For the Intel Composer XE 2011 the default download is the latest version 2011 Update 6.
Which is the version you actually installed?
So you need to download the Update 6 as I explained in the last communication. Please open the link from the registration email you got from the Intel Registration Center and choose Update 6 from the drop-down box in the download area.
For now you are fine with the Parallel Composer 2011 you are regsitered for and don't care about the different products.
You may have a look at the product page to sort out whether you may need the full package of compiler and profiling/correctness tools (Parallel Studio or Parallel Studio XE for Windows) or just the compiler tools (Parallel Composer or Composer XE).
