How to detect the version of the .NET Framework that is installed on the computer

To detect the .NET Framework version(s) you need to check the following registry keys:

  .NET Framework 1.0:
  Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\policy\v1.0
  Key: 3705
  Value (REG_SZ): 3321-3705

  .NET Framework 1.1:
  Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\policy\v1.1
  Key: 4322
  Value (REG_SZ): 3706-4322

  .NET Framework 2.0:
  Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\policy\v2.0
  Key: 50727
  Value (REG_SZ): 50727-50727

If you do that, there is no way to know if .NET is installed or not. MS recommended to use the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727 and then checking Install 1/0
