I have downloaded and run the file from that location.

A dialogue box opens.
Step 1, I select English for my language.
Step 2, I agree to the terms of use.
Step 3, it tells me it has successfully installed the software.
Step 4, it wants me to register my product.

Step 3 takes maybe half a second to complete. The installer is a 16mb file. It never prompts me where to install the file.

I have no Logitech folder anywhere on the system.
I do not have any icon on the task bar.
Nothing on the Start Menu or All Programs.
Seach for Logitech only brings up the installer file.
Search for Profiler finds nothing; the software used to be called Profiler.

Kind of stumped.
