According to the wiki page
But both the bat files still say 2.2d - latest haupauge from that linked page is 2.8aPlease note: The following bat files are configured for installing from WinTV7 v2.8a. For other versions of WinTV7 the bat file will need editing (in notepad) to change the version number of WinTV7 that has been downloaded.
I don't need it myself but it is causing confusion to new users.
Additionally - wouldn't it be better to rewrite the bat file and wiki page so that the installer and bat are placed in a folder in the root of C to run, rather than in program files - for UAC reasons? Especially with Windows 8
