I can't see anything obvious in your package file, though there is one or two things a bit "strange".
Have you called it "indylaz.txt" instead of "indylaz.lpk" for a good reason (may be to upload it) ? Are you sure that it is this file which is used during your package installation, and not an "old" .lpk file still present ?
Apparently, the version is not the latest one, though it's still a recent one, indeed. What I find a bit strange is that I've never seen a recent Indy file build this way: may be because you've changed some options in your IDE for this package and re-saved it ?
What I find strange, for instance, is that you have only 13 files count in your package file: in the past it was 15, and since a while it's 14 AFAIK: IdDsnCoreResourceStrings.pas is missing. Why ? And I've got 14 both for my Indy 10.6.0 (build 5141) and 10.6.2 (build 5273), while yours is 10.6.1 (build 5238): just between the two of them.
So, where did you get your whole Indy package, exactly ?
Just to be sure, have you checked inside your IDE that your package has really been installed as "RunAndDesign" in its option: see attached capture for my own version.
Sorry, I can't see any other "good" reason explaining your problem. As a last chance, you can eventually make a try with the current version of Indy, i.e:
- uninstall your current Indy package, then remove all the Indy files currently present (sources, binary, config...) into your Indy package subdirectory,
- download the latest version from
http://indy.fulgan.com/ (in ZIP directory - currently "Indy10_5274.zip");
- install it without any modification (you still need to compile it twice before rebuilding your IDE for it's final installation step).
BTW, have you also made a try with a simple test project by adding the absolute path of your Indy binaries into the search path of this project (-Fu compiler option):
Project - > Project Options - > Compiler options - > Paths - > Other unit files
