  • Hi Suljo,

     

    Welcome to the MSDN forum.

     

    First, could you please let me know your OS and Service Pack level?

     

    Second, you said you cannot find mscore.dll. Are you able to find mscoree.dll under folder “%windir%\system32”? if you cannot find it, I think the .NET Frameworks installed on your machine have corrupted already. I recommend you uninstall them all and reinstall them.

     

    Third, I also recommend you use .NET Framework Setup Verification Tool to verify the .NET Frameworks installed on your side.

     

    If you have many version of .NET Framework installed, I recommend uninstall 3.0 and 3.5. Then try to install 3.5 SP1. To minimize the number of separate downloads and installs – if you install the .NET Framework 3.5 SP1 first, it will automatically install the .NET Framework 2.0 SP2 and 3.0 SP2 for you, so you don’t need to install them separately.  Also, if you install older versions of the .NET Framework 2.0 and 3.0 before installing the .NET Framework 3.5 SP1, the 3.5 SP1 installer will automatically uninstall them as a part of its install process.  That means you will just end up wasting time if you install the .NET Framework 2.0 and 3.0 before installing the .NET Framework 3.5 SP1.

    You can download .NET Framework 3.5 SP1 here: http://www.microsoft.com/download/en/details.aspx?id=25150

    For more reinstall information, you can refer to this article: http://blogs.msdn.com/b/astebner/archive/2010/12/22/10108400.aspx

     

    I hope this helps.

  • Before trying again clear all the files in TEMP folder then follow the steps below. If the installation fails again, collect the logs "VSD* \ install.txt" in TEMP folder.

     

    For "error 25007 failed to install fusion"

    http://social.msdn.microsoft.com/forums/en-US/netfxbcl/thread/47c93410-2ee2-4dd1-812a-04475d50de7c/

    1. Do you have the COMPLUS_VERSION environment variable set?  If you do, remove it from your environment variable and try to install the framework.

    2. Rename mscoree.dll in %windir%\system32 and try to install the framework

    3. Look in your registry.  If you had a previous version of the framework installed (beta 1, beta 2, etc), see if this key exists:

    HKLM\SOFTWARE\Microsoft\.NETFramework\policy\v2.0

    Name: 50727

    Data: 50727-50727

    If you don't have that key, delete the keys that are there and try to install the framework.

  • ok, i already read that link and no luck
    i dont know what are you talking about COMPOUS_VERSION ??
    i dont have mscore
    i even dont have that registry entry

  • 1. Leave the step 1

    2. mscoree.dll can be located in system folder ( if you have any .Net Framework installed it will be there )

    3. The complete path of the registry is

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\Policy\v2.0\

    delete the key 50727 in it.

     

    You will need to clear this registry and then try again.
