Hello,

May be you hadn't installed plugin before? Or may be you have a firewall on your computer?

Thank you! Konstantin Solomatov

I have chose the directory "\plugins" and installed all of the files in it.

And I have shut down the firewall.Now ,my computer  even hasn't an anti-virus software.

But it still don't work.When I creat a new project,at bottom of the diologue,it shows a red message that IntelliJ IDEA with installed plugins isn't running.

What should I do now?

Check IDEA IDE settings -> plugins

You should have the "JetBrains MPS Integration" plugin installed.

If the MPS plugin is not listed check the \plugins directory. There should be subdirectory \plugins\MPSPlugin.

sometimes the MPS plugin is incorrectly installed in directory \plugins\plugins
