Install Components

There are many components available on the Internet that come as a single .pas file rather than a complete package project. This is how to install these:

Delphi 1-7

Use the Components -> Install Component menu entry to install the component into the default dclusr-Package.

all Delphi versions

Create a new package using the File -> New -> Other menu entry, add the component's unit to that package, compile and install the package

Step by step instructions:

1. File | New | Other... | Delphi Projects | Package, click OK
2. Project | Add to Project [add units and/or Requires items]
3. In Project Manager, right-click on Package1.bpl node and select <Install>

If you want the convenience of the old Delphi versions for Delphi 2005 and Delphi 2006 (and the Turbos): See Rudy Velthuis' VCL Component Installer
