IntelliJ shortly shows a splash screen and then disappears. I also had downloaded Android Studio after which also does the same. I'm not sure how to run IntelliJ from command, since I didn't find idea.exe in my bin folder, not sure where else it could be located. I'm running a Windows 7 OS. Help is greatly Appreciated.
Uninstalling the program, deleting the IntelliJ settings folder in "MyDocuments", deleting the IntelliJ folder in "Program Files" and Reinstalling a fresh new IntelliJ from the site resolved the issue.
