Discussion
The most accurate way to find whether a certain version of .NET framework is installed on the target system is to view or query the registry for values under a specific key path. Microsoft places all .NET related keys under the following subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDPAll of the .NET versions that are installed are listed under this NDP subkey and the exact version number is listed as in the value name Version.
NOTE: For .NET 4, the Version value name is under the Full or Client subkey under NDP.
NOTE: For .NET 4.5, the path is under the v4\Full under subkey NDP. There is a value name Release that indicate the exact version of .NET 4.5 or newer that is installed.
