I deleted Xcode and now want to reinstall it, but the App Store app says Xcode was installed. There was only one copy on my machine, and the only connected external hard drive only has Time Machine backups.
Edit: I tried holding down the Option key while in the Purchases pane, and I did not see an "Install" button next to Xcode.
