Hello singgihsatch... I'm sorry to hear about your problem/issue with trying to install Splinter Cell Conviction, but I will do my best to try and help. A "Cyclic Redundancy Check" refers to the DVD the Splinter Cell Conviction game is on... it can't be read; either the DVD disk is scratched/broken/data corrupt ect. or your DVD player on your PC is not functioning correctly... thus the CRC check. Take the Splinter Cell Conviction DVD out of the PC tray and gently wipe/clean and try again. Double-check that you PC DVD drive actually works by putting another DVD in and checking/ensuring it works properly. If after you wipe/clean the Splinter Cell Conviction DVD and double-checked that you PC DVD drive works but the game still won't install, then I suggest contacting Ubisoft Technical Support
http://ubisoft-en.custhelp.com/app/answers/list. Explain to them about the message you are receiving and I am certain that they will send you a link (via email) to download Splinter Cell Conviction.
Good luck.
