title: I cannot install TeeChart2013 for Delphi 7
body: <p>I cannot install TeeChart2013 for Delphi 7. 
  I did the following: 
  1. All the <em>tee</em> files were deleted from the Windows folder and its sub-folders.
  2. All the <em>tee</em> files were deleted from the Borland\Delphi folder and its sub-folders.
  3. The TChart component disappeared from the Delphi component library.</p>
  
  <p>Then I installed the TeeChart2013Delphi7.exe file, a trial version downloaded from the official web site.
  The installation went successfully and the component library displayed a new tab with the TeeChart components.
  After that, I created a new project, added TChart on an empty form, and compiled the project.
  The following error displayed:</p>

  <p>Then I added the TeeGDTPlus component on the form and specified the above Chart in its properties. I switched Active to true and then to false. 
  After that, I removed TeeGDTPlus from the form and its unit was deleted from the project’s  “uses”. The project compiled successfully but when the application run the following error displayed:</p>
  
  <p><img src="https://i.stack.imgur.com/7t3TV.png" alt="enter image description here"></p>
  
  <p>The same error was displayed in my other project which used the old version of TChart. </p>
  
  <p><em>"Error reading Chart.Legend.Shadow.Color: Property Shadow does not exist"</em></p>
  
  <p>When I install the 8th version of TeeChart it causes to the same results when I am running the project’s executable file:</p>
  
  <p><em>"Error reading Chart.ColorPaletteIndex: Property ColorPaletteIndex does not exist"</em></p>
  
  <p>I suggest that the old default Delphi 7’s TChart version still exists somewhere in dcu or bpl files. </p>
  
  <p>Please help me to achieve the correct TeeChart2013’s operation in Delphi 7.
  Thanks.</p>
