Plugin PLSQLDOC install error in win7 x64

[Mindaugas]

I could't install plugin PLSQLDOC on win7 x64. I tried administrator mode, setting compatability to windows xp sp2. Nothing helped. Is it fixable?

What exactly goes wrong?

Note that you can always unzip the file into the PlugIns subdirectory in the PL/SQL Developer installation directory.

Thanks. It appears that plugin anyway was copied to the right folder.Just to complete topic, here are images before install and after install.
