I have been trying to track down a problem with an installation of RAD Studio 2007 for some time. When compiling an ASP.NET application build with the .NET personability, I get an "[DCC Error] F1026 File not found error, where it reports that it cannot find a particular .dcuil file.
The file that is referenced in this error message is located in a directory that appears in the .NET library search path. The only work around I found was to add the associated .pas file directly to the project.
I finally found a correct solution to this problem. Please see my answer below.
