LA Noire installation

While installing this game I get an CRC error about some part cases_1_1.big.pc which doesnt match file in setups cab file. What to do with that?
I also get this error when I want to install GTA IV
Answer #1
Basically yo need to redownload the game. bcoz its a main file of this game and its aprox 5GB file
better to re download or use torent and select this specifc file.
thanx!
Answer #2
already downloaded from SKIDROW, SHITROW, RAZOR … always the same error
Answer #3
Did you download repack version? If yes then download full version.
And if you downloaded Full version then try to run setup.exe as Administrator.
Fyi, This game has error in installation. My friend downloaded the full version but he can’t install it whereas I successfully installed in my PC, patch & Cracked the same.
Further, Arfarsh is right, You must download specific file from Torrent.
Answer #4
It was full version.
But I will try to download that specific file. thanks to both of you for an advice
