OK I have just moved house and we got broad band installed. I used to have half life on my old computer but it was too slow for counter strike or other paintball plugins so I just tried to install HL on my new (made of other parts so not brand new) PC so I could do this nad it just doesn't want to know, It just stops at 55% when installing and if it does install then I get a error message kinda saying no key board installed (but bot quite that simple and it is is a HL dialog box)
It is a legit bought version of HL so I am stuck and confused
