I opened a component I had written in Delphi 7 within Delphi XE3 and tried to compile and install but I receive the message 'File not found: DesignEditors.dcu' . In the editor DesignEditors and DesignIntf are red underlined. These units are inclued in the unit I use to register component.
But if I open a package which contains all my components (all... they are only 5), with the exact same source, I can compile and install without problems!
I need to solve because I want distribute components individually, not as a suite.
Googling I found several suggestions but none has solved the issue.
Thanks in advance for any advice.
