Too many Visual C's installed??

Question

Hello.

When I look at the software-list of my Windows 7 64bit computer there seems to be a lot of Microsoft Visual C's installed. I wonder of this is correct? I have the feeling that when I install a new game, it sometimes automatically installs another version of this 'Visual C-program'. (of which I don't even know what it's meant for)
Isn't one version enough?? Should I take action in some way?

Here's a list of the 'versions' which are there;

Microsoft Visual C++ 2005 ATL Update kb973923 - x64 8.0.50727.4053
Microsoft Visual C++ 2005 ATL Update kb973923 - x86 8.0.50727.4053
Microsoft Visual C++ 2005 Redistributable (version 8.0.56336)
Microsoft Visual C++ 2005 Redistributable (version 8.0.59193)
Microsoft Visual C++ 2005 Redistributable (x64) (version 8.0.56336)
Microsoft Visual C++ 2008 Redistributable - x86 9.0.21022

Further down the list there are also these (which are apparantly from Grisoft and AVG)

Visual C++ 8.0 Runtime Setup Package (x64)  (version 8.0.0.35) Grisoft s.r.o
Visual C++ 8.0 Runtime Setup Package (x84)  (version 9.0.0.623) AVG Technologies CZ, s.r.o

what to do? I wouldn't like to find out that some games don't work anymore after deinstalling something of course..

Answer 1

As you may have noticed, there is a version difference amongst all the installed redistributables.

Redistributables are installed side by side in an SxS folder and is bound to an application using a manifest file.

So uninstalling one version will effect the application dependent on that version.

I noticed the difference yeah but wasn't sure. So nothing is wrong. That's a relief.

Thanks for your reply.
