title: What does "error RC2175: icon.ico is not in 3.00 format" mean
body: <p>I recently ported a project from VC6 to VS2012, fairly successfully.  Trying to change out the splash screens and icon that were previously bad looking bitmaps.  From the looks of it, 256 color bitmaps.</p>
  
  <p>So, I made new bitmaps and tried to put them in and constantly get:
  error RC2175: icon.ico is not in 3.00 format</p>
  
  <p>I've searched for what this means and got:

  <a href="https://stackoverflow.com/questions/3384430/error-rc2175-resource-file-res-icon3-bmp-is-not-in-3-00-format">error RC2175 : resource file res\icon3.bmp is not in 3.00 format?</a>
  And the worthless MSDN page.</p>
  
  <p>I tried making these bitmaps as 24-bit, 256 color and 16 color.  I also tried all the different modes Gimp allows mimicing the other, original icons.  Also tried loading the bitmaps in MS Paint and re-saving without success.</p>
  
  <p>And this point, I would just like some indication on what 3.00 format is and how to get around it.</p>
