dbclick idea(64).exe no response.


The idea crashed a hour ago, and I couldn't open it again. When I dbclick the idea.exe, no response, no idea.exe found in Windows task manager.

Best regards!

Try to reinstall from http://www.jetbrains.com/idea/download/index.html and remove IDE folders to start with the defaults: https://intellij-support.jetbrains.com/hc/articles/206544519.

If it doesn't help, try running using idea.bat in cmd.exe console to see the actual error that may help to fix the problem.
