Windows 7: multiplie "Microsoft Visual C++" installation

hi guys

i had few problems with Windows 7 after i moved from xp

some games wouldnt run so i updated my DirectX + Microsoft Visual C++

but i think i gone too far and i installed too much Visual C++ clients

i have 4 2005's: 2005 x86 + 2005 x86 ATL update,. +2005 x64 +2005 x64 ATL update.

plus i have 3 2008's:2008 x86 +2008 x64 + 2008 x64 ATL update


2 or 3 i have installed on my own .(after i installed 64bit version i would get update for it from Microsoft)

can it harm the system?

which i dont need?

which i can remove , without causing system problems?

You do not need to uninstall them, because some others applications might reinstall them anyway. They do not take that much space...let it be!

ok

can it harm the system that i install something manual without program\game windows update request?


what about clients clash?

and why i need ATL update, as much as i understand its for developers or something?!

No, you can install ALT Updates & aswell SP1 pack for both 2005 - 2008.

You also can install manually all you need for visualC++ but as i said some apps might replace older install.
