Aubrey,
He is running XP.
All of my files use relative paths.

I use DevPacker.ListLoadedModules to create the
list for DevPacker.PackThis.

I first run my application in the development environment and
exercise all of its functionality and then call DevPacker.ListLoadedModules.
In this way embedded bitmaps are included in documents and so
are the necessary handlers for Forms. I, of course, append my resources
and documents to the list.

If I instead use DevDependencies.CreateTool then the generated list is
incomplete.

 From the documentation for DevPacker I find
"Absolute vs. Relative paths in filenames
Imagine that BlackBox is installed in directory D:\BlackBox. Then the
file name D:\BlackBox\Std\Code\Log.ocf (absolute path) denotes the same
file as Std\Code\Log.ocf (relative path) as far as the packer is
concerned. But the packer packs the file into the exe-file with the path
given in the command. This makes a crucial difference for
HostPackedFiles which reads the exe-file. If the exe-file for example is
started in directory C:\temp, and the program makes a call to StdLog,
then this command will work if the file was packed using a relative
path, but not if it was packed using an absolute path. On the other
hand, if the file was packed using an absolute path, a call to open file
D:\BlackBox\Std\Code\Log.ocf will work even if no physical drive called
D: is present on the machine."

Hence I would expect that no matter where my client puts the EXE file it
should run.
I just opened the EXE file in data mode and scanned for "c:" and did not
find any paths with such.

Thanks Aubrey for the heads-up on absolute paths.

I'm still not sure what is going on.
