How can i install and launch calibre portable on Windows 7?

Question

I tried downloading and installing calibre portable in a new folder, in the "documents" library on Windows 7.

however the program doesn't launch (open) when i double click calibre-portable.ext. instead the arrow (mouse) shows the loading/processing symbol for about 7 seconds.

where did i go wrong?

update

it worked well on a SD card. however i believe it would work quicker on the computer itself.

From the official website:

To use, just run the portable installer and select the location where you would like the Calibre Portable folder.
To launch calibre, double click the calibre-portable.exe program inside the Calibre Portable folder.

The problem may be that you installed to the Documents folder, which has been said to cause problems.
