I am trying to install .net framework 4 but have I to first to turn off the features in windows. When I try to turn off Window features through the Control Panel, I get the error message "An error has occured. Not all the features were successfully changed. How do I make it so I can turn off the features so I can install framework? Thanks

I have installed .Net 4 via Visual Studio 2010 and haven't had to 'turn' any features off. You should be able to download .Net 4 and install it as normal.

copy the file "C:\Windows\Logs\CBS\CBS.log" to your document folder (otherwise you can't open it) and open it with notepad. Now search for errors. Which errors do you see? If you are unsure, upload the file to your SkyDrive and post a link here."A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Hi, It may occur if some system files are corrupted. I suggest performing System File Checker first: Use the System File Checker (SFC) =========================== 1. Click Start, type "cmd" (without the quote) in the Start Search bar, right-click cmd.exe and click run as administrator. 2. Input the following command and press Enter. sfc /scannow If it persists, perform a repairing installation: In-Place upgrade (Repair install) =========== 1. Start the computer by using the current Operating System. 2. Insert the Windows 7 DVD in the computer's DVD drive. 3. Use one of the following procedures, as appropriate: If Windows automatically detects the DVD, the Install now screen appears. Click Install now. If Windows does not automatically detect the DVD, follow these steps: a. Click the Start Button, type Drive:\setup.exe in the start search box and then click OK. Note: Drive is the drive letter of the computer's DVD drive. b. Click Install now. 4. When you reach the "Which type of installation do you want?" screen, click Upgrade.Vivian Xing - MSFT
