Installed PC game successfully but no files copied except 2 shortcuts to nothing!?

I installed Hitman 2: Silent Assassin a PC game, the installation wizard said that everything was successful…whent it wasn’t. I clicked on the hitman shortcut that was created on my desktop but
it said windows is trying to locate hitman2.exe so my option was to click browse.

I went to Program Files, went into the Folder the files were meant to be copied in but there was NOTHING?

So I can’t play Hitman 2 even though it’s “installed”

I tried uninstalling it but I couldn’t because there is no file to uninstall it!

Could anyone help please, thanks.

Computer Details:
Windows Vista Home Premium (I set it to run for Windows XP as Hitman 2 is rather old)
32-bit OS
