Intellij idea installation

Hi,

Please try the following:

1. Close your project window (and IntelliJ) and remove all *.iml files and the .idea folder from the project directory.
2. Re-import the project into IntelliJ from existing sources.

You can also try deleting the IDEA system directory altogether, then re-importing your project.

If the problem remains please temporarily disable all downloaded plug-ins, remove the logs, restart the IDE, reproduce the problem and provide the logs generated by Help | Collect Logs and Diagnostic Data.

Intellij is not getting open its showing class not found

Where is it showing it? Can you attach a screenshot?
