Just found that via Google, same problem here on Win7 with the LSGG installer. I use Avira Antivir and PC Tools Firewall, both turned off.

Thereafter every single file being installed is listed, as well as the files already exists, as the uninstaller doesn't seem to work properly either.
On my Vista system a few weeks ago it worked perfectly. Seems to be a Windows 7-issue.
A pity, as I wanted to fly from Geneva to the IVAO Real Flight Event in frankfurt.
