title: Delphi 10.3.2 - Cannot resolve unit name System.Classes
body: <p>Brand new installation of Delphi 10.3.2</p>
  
  <p>Error Insight reports errors 'Cannot resolve unit name' on core RTL and VCL units, like System.Classes</p>
  
  <p>This pollutes the error insight report, and also blocks code completion (control+space) which is a real issue...)</p>
  
  <p>What I have tried so far:</p>
  
  <ul>
  <li>Create a new VCL Form project: Same error, but project compiles without error</li>
  <li>Checked that Control+Enter open the source file: ok</li>
  <li>Checked that source folders are declared in the Browsing path (general Options)</li>
  <li>Added the source folders to the Library path (general Options)</li>
  <li>Installed IDE Fix Pack for delphi 10.3</li>
  <li>Uninstalled previous delphi versions (XE4 and 10.2)</li>
  <li>Cleaned the system PATH variable by removing references to previous delphi installations</li>
  </ul>
  
  <p>I'm out of idea on how to fix this issue. Any help would be greatly appreciated</p>
  
  <p>Edit: When switching to Win64 platform, error insight errors are gone. So I tried to delete the Win32 platform, and re-create it:same errors happen again.</p>
  
  <p>Edit2: I uninstalled and installed Delphi 10.3.2 again: The error is still there...</p>
