When your Delphi XE Browsing Path has been destroyed Ken White to the rescue (via: Stack Overflow)
Posted by jpluimers on 2013/08/11
Something overwrote the Browsing Path of my Delphi XE installation.
Symptoms:
- When debugging a project in “use debug DCUs” mode, the IDE cannot find RTL, VCL and Indy units.
- When you type `System` in a source file, then press `Ctrl+Enter`, the IDE cannot find the source code to the `System.pas` unit.
It was faster to examine the Delphi XE Library registry settings from Ken White than comparing them with a backup or a fresh Delphi XE install.
Now it works fine…
