Error Disk 5 Halflife 2 Help

[Robbie_Crews]

I just bought Halflife 2 Game of the year edition. It seems that on disk 5 when installing the Hl25.cab, I get an error saying error 1334 and it tells me something couldn't be found in Hl25. What do I do?

You probably declined installation of Counterstrike Source.

You need to install it as well, and then delete it afterwards if you don't want it. Some HL2 files are mixed in with it.
