Compilation error

[Loic via Digitalmars-d-learn]

Hello,

I hope it's the good place to ask my question.

I'am trying an hello world program in D, unfortunately the 
compilation, doesn't work, and found nothing on google.

when I do : dmd Hello.d, the error returned is

Error: cannot find source code for runtime library file 'object.d'
dmd might not be correctly installed. Run 'dmd -man' for 
installation instructions.
config file: C:\D\dmd2\windows\bin\sc.ini
Specify path to file 'object.d' with -I switch

My machine is Windows 7 64 bits DMD2 and DMC are installed.

Thank you

Loic
