I tried to install Xcode 4.3.2 from application store, after clicking the Install button, a message displayed as "Installing". (but no progress bar appeared)
After about 30 minutes, (while installation was on progress), my Mac crashed and I had to turn off the power and restart it again.
Now, if I try to install the Xcode again, nothing happens (see the image) after I click the install button except the Apple store login dialog pops in and ask to login.
(No folder named "Developer" has been created in my Application folder yet)
