Path to BPL files

I am just curious about something I have noticed when installing 3rd-party
libraries. In some cases it is necessary to copy the BPL files from the
Delphi\Projects\BPL folder to \Windows\System32 or the package will not
load. In most cases this is not necessary. What determines whether this
needs to be done?

The directory $(DELPHI)\projects\bpl has to be in your PATH environment

variable and there will be no need to copy the package in
$(WINDOWS)\System32.

Thanks, that works. But now I notice that for some packages the BPL exists

only in Windows\System32, and for others only in Projects\BPL. The location
where they are originally installed doesn't seem to be consistent, which I
find strange. Is there something in the package setup that determines this?

The place for the BPLs is determined by two places

1. The place where the toolbox installer puts them
This is the most common source for the ones in
$Windows\System32
2. The directories specified in the project options dialog
BPL output directory
DCP output directory
This is the source for the ones in $Delphi\Projects\BPL
Windows imposes ever stronger limitations on the place where files
can be positions. For all sub directories of either the Windows
directory or the program files directory you now need Administrator
privileges which only installation programs will have under Windows
Vista.
