TWO instances MS Visual C++ 2005 ​Redistribut​able on Win764bit machine?

I'm wondering how it's possible that I have 2 versions of microsoft visual c++ 2005 redistributable.
The strange thing is that the one with the newest install date has an older version number.
I'm pretty sure this is something that the Rockstar Games Social Club application (or Grand Theft Auto 4 itself) installed. They both have the same install date.
I uninstalled the game a few days ago and I don't think it uninstalled correctly.

QUESTION:
Is it possible for me to just remove the one with the old version number OR can I remove it all and re-install MS Visual C++ Redistributable again?
If so, what would I download for a Win764bit machine?
Here's some screenshots with version numbers and install dates.

You could uninstall one that you know isn't used for anything except for the software you've uninstalled.  Just make sure you have the install for the software you have installed in case your wrong.

2 isn't so bad

Well, I'll uninstall the Social Club thing first and see what happens. Like you said, the one that was installed on the same day as GTA4 probably isn't important so maybe someday I'll dare to get rid of it too.

I'm guessing if I didn't have ANY VC++ 2005 redistributables I would install http://www.microsoft.com/download/en/details.aspx?id=18471

I see that you have the exact same ones as me (plus a few more).
Which version number is the one that's 2.69MB?
Mine is 8.0.56336

@dentaku: That's the one.

don't remove them. With WinSxS, DLLs can be stored in several versions side by side and the app uses the version it was compiled against (DLL hell from Win9x)
