Hello folks,
It seems that the default directory layout fallback is not working as expected.
When installing POV-Ray 3.7 with INSTALL-DIR and USER-DIR pointing to the same
directory the installer puts everything in the install dir and nothing to the
user documents directory. Running POV-Ray then works just fine. However if you
then make a backup copy of the directory and uninstall POV-Ray and then run it
from the prevously made backup directory it will tell you with a dialog
something like:
POV-Ray is not installed.
Using default directory layout.
Directory ***** is default directory.
While previous versions prior to 3.7 then worked fine the current version won't
find the include files because it searches for them in the user documents
folder.
It doesn't use the default directory layout nor it uses the user-dir given
during installation.
I used the default directory layout fallback with previous versions to make a
portable version of POV-Ray which I could put on an USB-Drive without the need
to install POV-Ray on the system.

Just so that we're on the same page here: Be aware that there is an OLD
default directory layout and a NEW default directory laout.
The v3.6 (and earlier) default layout had the sample scenes, include
files and master INI files inside the program's installation location.
The v3.7 (and later) default layout has the sample scenes, include files
and master INI files inside the user directory.
This change was made because since Vista, users no longer have write
access to the program directory (not without hassle anyway); so it would
have been a pain to change the master INI file, or even just render a
sample scene for giggles.

Yes, that is to be expected: The choice of INSTALL-DIR and USER-DIR is
normally stored in the registry; uninstalling will also wipe out this
information.
If you then run POV-Ray without properly installing it, POV-Ray will
again presume the (new!) default locations for INSTALL-DIR and USER-DIR.

Previous versions didn't have to make this distinction.

It /does/ use the new(!) default directory layout; that's exactly what's
causing you trouble. And what installation? Since you've uninstalled.
that installation you had done much earlier remains nothing more than a
fever dream.

Yes, the bad news is that POV-Ray v3.7 does not support "portable
installation" (or whatever you want to call it).
This leaves room for improvement, but it is not a bug.

First thanks for the reply and the detailed explanation. I personally don't
understand why the team had to make the user-documents folder the new default
directory layout. Onestly this negiglates the sense and purpose of a "default
directory layout" as it would only make sense when it would take grip only when
POVRay is NOT installed and has written NOTHING to user documents directory.
This is exactly the message I get from the dialog at the first start.
And btw. the dialog tells me that the new default directory is indeed the new
backup
directory. So someone is now lying to me and it seems it's the dialog about the
new default directory.
