When you call up the REPAIR command, the commands are executed to clean and correct the file.

At the end, there are a series of recommendations according to what the user may be working on. 

The file should be saved, closed and reopened to work in a clean environment.

The installer that ran when you downloaded this app/plug-in from Autodesk App Store will start installing the app/plug-in. OR, simply double-click the downloaded installer to install the app/plugin.

You may need to restart the Autodesk product to activate the app/plug-in.

To uninstall this plug-in, exit the Autodesk product if you are currently running it, simply rerun the installer, and select the "Uninstall" button. OR, click Control Panel > Programs > Programs and Features (Windows 7/8.1/10) and uninstall as you would any other application from your system.

I send the source code in case some people are encouraged to add and report commands that contribute to improving the work files.
