how to set plugin folder security permissions in SketchUp

If you ever get SketchUp startup error-messages relating to plugins? This usually means that some plugins are not loading properly and it indicates they have not been installed properly.

Or maybe you get system messages actually preventing you from adding/managing files/subfolders to the Plugins folder in SketchUp. This guide will help you identify the problem and fix it for both Mac and PC devices.

The complete guide to fixing Security Permissions for SketchUp

start up errors in SketchUp

These startup errors and system messages are typically related to a 'Security Permissions' problem with your Operating System. Modern Operating Systems tend to protect you from inadvertently adding files into a program folder structure. Unfortunately, when it comes to installing plugins and extensions in SketchUp, this is exactly the situation we find ourselves in. How can you fix the Security Permissions on Mac and PC for SketchUp? Here's our quick guide...

How to fix Security Permissions for SketchUp Plugins folder on Windows

If you have limited Security permissions to your Plugins folder, Windows can let you think it has installed your files properly, but it has actually put them [or the subfolders needed by them] into a place called the 'VirtualStore'.

Compatibility Files indicating button in Windows

If the Plugins 'Windows Explorer' window has a link/button in its top-bars named something like 'Compatibility Files...', then that is a sure sign of this - clicking on it opens the VirtualStore revealing what has not been installed properly.

Being an Admininstrator on Windows is no guarantee that you will have adequate permissions - by default Windows limits the Security setting of everyone, for all files and folders within the 'Program Files' tree.

NOTE: If you get a message from the SketchUcation 'Plugins Manager' itself saying things you have no Plugins folders to manage in the $LOAD_PATH, this is because of the same issue.

It will not let you 'manage' plugins in folders for which you have inadequate Security permissions - if it didn't stop you, then you would think you had disabled a plugin only to find that you hadn't when SketchUp restarted, because you did not have permission to change plugins. You have been duped!

Here are the steps you need to fix this...

  • As an Admin [if you are not one give yourself that ability under the Users Control-Panel...]
  • In the very unlikely event that you have a custom icon assigned to the Plugins folder remove it - oddly this can subtly change even its FULL permissions just a little, and has been known to cause issues
  • Restoring default folder icon in Windows
  • Select the Plugins folder's icon, in the SketchUp folder
  • Right-click > Context-menu > Properties > Customize > Change Icon > Restore Defaults
  • Apply/OK

Now to fix your Plugins folder permissions...

  • Select the Plugins folder's icon, in the SketchUp folder
  • Right-click > Context-menu > Properties > Security > Edit
  • Editing Security Permissions in Windows
  • Set the permissions for every user/group in the list to FULL read/write
  • Apply/OK

These changes should automatically trickle down to affect the contents too. So all the files within the the plugins folder will inherit the FULL read/write permissions.

Next is to set SketchUp to always run as admin...

  • Select the SketchUp.exe icon, in the main SketchUp folder
  • Right-click > Context-menu > Properties > Compatibility
  • Setting Run as Admin in Windows
  • In the 'Setting' pane tick the check-box 'Run this program as an administrator'
  • Apply/OK

If you have previously properly relocated the missing Plugins folder's files/subfolders-with-files-intact from the VirtualStore... or deleted them and then reinstalled the plugin[s]... then the SketchUp startup error-message should be history.

After the SketchUp restart the SketchUcation 'Plugins Manager' should also work and list the contents of the main Plugins folder, which you will now be able to disable/enable, with the changes remembered across sessions.

Now when installing plugins and extensions it should put every thing in the correct places - and hopefully leave the VirtualStore empty!

Hopefully, SketchUp versions >v2013 will address this permissions issue and locate the Plugins folder in the User's AppData tree, where they will automatically have FULL permissions. But until then you will need to grant Security Permissions to allow SketchUp to make changes in the plugins folder.

How to fix Security Permissions for SketchUp Plugins folder on Mac

Most MAC users will usually already have FULL access to their Plugins folder, because it is in the User's Lib tree. But for SketchUp versions <v2013 they can also experience these limited permissions issues - much as described for PCs - because in those versions the default Mac Plugins folder was in the automatically restricted main HD Lib path.

This can be fixed in a similar way:

  • Select the 'Plugins' folder's icon [press Option-key in the 'Finder' to see these Libs listed]
  • Use the context-menu > 'Get Info'...
  • Its 'Sharing and Permissions' pane should show FULL read/write for you [and others if you wish] - but if not you should reset - you might have to enter the admin password if it is 'Locked'...
  • Note that unlike Windows - where the changes to the permissions of a container [folder] automatically trickle down to affect its contents - on a MAC you must select the 'cog' dropdown option - 'Apply to enclosed items...'

Now with your plugins folder set to FULL read/write you should have no problems installing extensions and plugin into SketchUp using the PluginStore in SketchUcation Tools.
