Half-Life 2+Counter-Strike: Source RETAIL Offline Installation, Decryption+Execution

[prakhargr8]

Hi.. This question is being asked in several threads but with no 100% working solution.

I have a 5 CD set(Original) of Half-Life 2 which naturally includes Counter-Strike: Source. My problem is I do not have any access to Internet from my gaming computer which is set in my dorm room. I want to install and run Half-Life 2 AND Counter-Strike: Source offline and I am willing to decrypt the files using any offline decrypter even if it takes 45 minutes or more.

How can I do so?

I would like some help regarding this matter.

I would also like to take your attention towards this thread.

If someone has tried this procedure please let everyone know whether it works or is it flawed.

If someone can mail me the attachments to prakhars(at)kis.ernet.in, I can verify it myself. My internet access features restrictions keeping me away from downloading files with *.exe, *.zip, *.rar etc. extenetions so I cannot download the attachments from the thread.

Please help me make this thread useful for everyone who wants to install and play Half-Life 2 and Counter-Strike: Source offline.

THANKS IN ADVANCE!
