Installation

The basic installation of the component is pretty straight forward:

1. Copy all files apart from README.TXT into the LIB folder or a subfolder
2. Add the file marqueereg.pas to one of your design-time packages or create a new design-time package for the component as described in Delphi's help files.
3. Recompile the design-time package

The more sophisticated installation takes a little more work:

1. Copy all files apart from README.TXT into the LIB folder or a subfolder
2. Create a new run-time package as described in Delphi's help files. If you are already using a run-time package for your components you can use that package.
3. Add the file marquee.pas to this run-time package and recompile the package.
4. Create a new design-time package as described in Delphi's help files. If you are already using a design-time package for your components you can use that package.
5. "Require" the run-time package you created or used above, if not already the case (see Delphi help for details on "requiring packages").
6. Add the file marqueereg.pas to the design-time package and recompile.

"DsgnIntf not found"

If you get this error, something wrong happened during the installation. The unit DsgnIntf is not shipped with Delphi 5/6 anymore, which previously provided classes for property/component editors. Now this unit is only included in one of Delphi's standard packages. Thus, you must now make sure that run-time packages include only run-time code! If this error occurs during the installation, you're trying to add the marqueereg.pas unit to a run-time package, which is not allowed. In that case, use the marquee.pas unit instead and create a special design-time package as described under "Installation".
