Windows 7: Microsoft c++ 2005 redistributable error + .net Framework 3.5.1. error

Hi.. wasted a lot of time.. but can't solve this.
Firsly, I installed new Windows 7 Ultimate (32bit), then i did all windows updates, but wasn't able to install MS Office 2007 or 2010 and then wasn't able to install Visual Studio c++ 2010. Couldn't find any solutions and tried to reinstall Windows 7 OS.
Now I reinstalled it and without windows updates firstly installed Office 2010 and Visual Studio 2010 - all was ok, no problems with installation.
Then i need to install another program which need Microsoft c++ 2005 redistributable.. and it can't install it and i tried to download and install manually vcredist_x86.. but it can't be isntalled and got error: http://www.bildites.lv/images/xejudwd8g3zt9xjn44b.jpg
I tried clear win boot, then i deleted Visual studio, all frameworks and redistr. too.. but it doesnt help. Then I payed attention, that ther ein windows updates can't be installed 4 updates and one of them is .net Framework 3.5.1. which also can't be installed..



Can you help me? I tried many solutions.. it seems that there is a conflict between Visual Studio c++ 2010 soft and .net Framework 3.5.1. or maybe VS or Office conflicts with Microsoft c++ 2005 redistributable... I don't have hope anymore to solve this on Win 7.
