I bought this gaming laptop this year in feb, and i have played a fair amount of games in it(6-8 games), but after a short break of not playing, whenever i try to install a new game i bought, the setup keeps failing stating isdone.dll error , unarc.dll error code 12, and for every different game i try to install, a different or same error code appears. and i have scavenged every bit of the internet for solutions and i tried it, right from increasing virtual memory to resetting and reinstalling windows totally, still my problem is not solved , kindly help..

When you run game installer, open task manager and see how much memory is consumed.

Are you installing original games?
If not file verification may fail and there is no solution for this.

EDIT:
It appears these dll's are part of an archiver and from what I know game companies don't use archivers to redistribute their games.
You can purchase those games or contact developers on steam.

I bought these games
From a seller and it was stated that it was original games , as I don't know much about pc, I also didn't enquire much...

There are 2 methods to verify game:
1. right click installer executable -> properties -> digital signatures -> click on signature -> details -> view certificate -> certification path

You can take a full screenshot of certification path AND properties -> digital signatures dialog for one game, and post it here, it's probably the only way for us to verify we're not helping with pirated software:

2. Verify site used to download game, for example GTA SA is bought here:
Rockstar Games: Grand Theft Auto San Andreas

maybe you took a look at wrong file, can you take a screenshot of installer directory containing game files please?
