title: Delphi: EReadError with message 'Property Persistence does Not Exist'
body: <p>My program written with Delphi 7 compiles OK, but when I run it it gives me the error message:</p>
  
  <blockquote>
    <p>Project1.Exe raised exception class EReadError with Message 'Property Persistence does Not Exist'. Process Stopped.</p>
  </blockquote>
  
  <p>This only started after I installed the TMS Component Pack to use with this project. Thanks for any help.</p>
