problem in installation AUTOCAD 2012

[Anonymous]

i am hansanee mago, an architecture student.

i installed autocad 2012 recently.

while installation process there was some configuration error but then it somehow got installed.

when i tried to open it, a window came (initializing window) for about 10 sec and then it disappeared and it didnt open.

i have tried reinstalling also but no change.

i am in desperate need of help as i have my submissions on hold.

early response will be highly appreciated.
