Installing a second language version of .NET Framework will lead to the following error: "setup was unable to install the Microsoft .NET Framework because another version of the product is already installed." If you want to use a non-English platform or view .NET Framework resources in another language, you must download the appropriate language version of the .NET Framework language pack.
