#994 obminimize gives warnings

[Pent]

To reproduce:

obminimize 4047.mol
It reports

==============================
*** Open Babel Warning  in OpenBabel::OBGlobalDataBase::Init
  Cannot initialize database 'types.txt' which may cause further errors.
==============================
*** Open Babel Warning  in OpenBabel::OBTypeTable::Translate
  Cannot perform atom type translation: table cannot find requested types.
==============================
*** Open Babel Warning  in OpenBabel::OBTypeTable::Translate
  Cannot perform atom type translation: table cannot find requested types.

However, then it continues with

A T O M   T Y P E S

and outputs seemingly-correct optimized structure.

Open Babel 2.4.1 -- Oct 10 2016 -- 21:23:29

I'm on Windows 10. Reproducible with both 32-bit and 64-bit binaries.

The environment variable BABEL_DATADIR is either not set, or pointing to a location that does not contain those files. It should be set, by the installer. If you could open a new command prompt and check whether it's set correctly, that'd be appreciated. echo %BABEL_DATADIR% will do the job. I don't have a Win 10 machine to hand, so I can't help much beyond this.

Ah, it works in a new command prompt without warnings!
Please close.
