Visual D cannot build Phobos Browse Info

[DLimited via Digitalmars-d-ide]

Alright, I need some help because I feel mighty stupid at the 
moment. Please do keep in mind that I just now started up with D 
and Visual Studio in general.

I'm using VS2012 Ultimate with Visual D. During my test project I 
noticed I did not get any value help / displayed info on neither 
the Gtk framework, nor the standard library.

So, it seems to me all the displayed documentation is stored in 
some JSON file somewhere. The "Generate Phobos Browse Info" is 
supposed to generate them for the phobos library, however it 
fails with the following message:

>> Building phobos JSON browse information files to 
>> C:\Users\DLimited\AppData\Roaming\VisualD\json\
>> dmd.exe not found in DMDInstallDir=C:\dmd\dmd2\windows\bin\ or 
>> through PATH

DMD is actually located in that directory, though - as well as in 
the path. Starting a random command line knows dmd; also my test 
project compiles (and it can't possibly compile without a 
compiler, can it?)

I have no idea what the actual generation process is, so I can't 
do it "manually" and place in the JSON import path either.

So, I'd love some help with this, I am at my wits end. I have no 
idea what the problem could be, because the displayed cause 
cannot be true unless the command fucks up the execution 
environment somehow. It also cannot be a read/write error because 
writing to AppData is always allowed.

Kind regards,
