This issue is caused by Windows Embedded Point of Service SP3 systems having a newer version of WMPHOTO.DLL than the .NET 3.0 installer is carrying and which causes the .NET 3.0 installer to fail. 

A successful install of .NET 3.0 can be accomplished after completing the following steps:

  1. Launch a Command Shell
  2. CD %windir%\system32
  3. regsvr32 /u wmphoto.dll
  4. ren wmphoto.dll wmphoto.dll.old

Now you can install .NET 3.0 with no errors!
