Failed read rbe/rbs file

Ok, I have seen this issue posted many times and many places. I have yet to find a solution that works for me, and all of the links I have found end without anyone posting that they have found a solution for them. I’ve been having the same problem since SU 2017, and I am posting what looks like the same startup errors that I have seen over and over again. Any brilliant new solutions?

To me these errors suggest that you might have installed SketchUp incorrectly.
In such cases file/folder permissions can be flaky and cause unpredictable issues…

Here is the correct way to install/repair your installation.
You should be logged into your normal Windows user’s account [i.e. “Gabriel”]
Exit SketchUp if it’s open.
Find the SketchUp installer’s exe file - in your Downloads folder ?
Select its icon.
Right-click > context-menu > “Run as administrator”…
When prompted choose “Repair”.
[If it’s a fresh installation choose “Install”…]
Restart SketchUp and see if the issue repeats…

Installing any complex app like SketchUp in any other way will ultimately lead to unexpected issues…
e.g. Never double-click the installer’s exe file to Run it - even if you have admin-powers it is NOT the same thing as using the correct “Run as administrator” method…


I have tried this several times. I agree that it looks like an incorrect install. I have also tried uninstalling the whole thing and reinstalling. I am sure there are some files I need to uninstall manually as well, and I probably missed them.

The user’s …/SketchUp/…/Plugins/ folder etc might have its permissions skewed by the earlier installation.
A full uninstall will leave the folder in place - especially if you have custom extensions installed.
Find the C:/Users/Gabriel/AppData/Roaming/ folder
It’s hidden by default, but using the full path in a Windows Explorer window should get you to it.
Find the enclosed SketchUp/ folder.
Right-click on its icon > Properties > Security > Edit
Ensure every entry has unlimited [Full Control] set up.
Allow the changes to permeate down to all contained subfolders and their files etc…

I suspect that your current settings are preventing SketchUp from fully accessing files in the Plugins subfolder etc…

After that try rerunning the Installer exe in right-click “Run as administrator” mode, and choose Repair [which will hopefully then work !] - finally restart SketchUp to see what happens…

All of the permissions were set properly, and I followed all of the steps several times to make certain that I wasn’t missing anything. I finally tried again to uninstall SU and start clean, but I was unable to completely uninstall SketchUp and all the files that kept causing problems. Out of frustration I performed a wipe on the whole computer (after I backed up all of my files, of course) and reinstalled everything. I was pretty sure that it was a Windows problem, and I was right. SketchUp runs fine now, and all of the errors are gone. I certainly wouldn’t recommend this as the first solution, but if all else fails…

I have the exact same problem (with SketchUp 2018), and there is no way I can wipe my computer to solve it like Gabe did.

I’d therefore be grateful for ideas on how to fix this in any other way. I have already done a repair installation exactly as described above – to no avail.

I eradicated everything Sketchup from the entire computer.
Reinstalled SketchUp 2018 from scratch (using “Run as Adminastrator”) on the Setup.exe).

Manually maximized permissions on the folder
C:/Users/[Username]/AppData/Roaming/SketchUp/SketchUp 2018

Copied over that entire folder from another PC (where Sketchup 2018 works).

Still get the same errors:

What is the problem here. This does not seem to have been resolved, ever?

If at least I could make my 3DConnexion SpaceNavigator work in SketchUp!

It however doesn’t seem to load also that extension properly:

“Error Loading File C:/ProgramData/SketchUp/SketchUp 2018/SketchUp/Plugins/3DxSketchUp/3DxSketchUpExt.rbe

Although the 3DConnexion extension does turn up seemingly properly in SketchUp:

I’m out of any ideas on how to fix this

Errors loading those plugins can happen, in general it is isolated. they belong in the program files folder. the rest of the entensions belong in the C:\Users…\AppData\Roaming\SketchUp\SketchUp 20xx\SketchUp\Plugins folder.

Which folder did you copy. Best practice is to install extensions from the sources to ensure you get the latest versions.

What you show for the 3D Connexion plugin looks normal.

This one:
C:/Users/[Username]/AppData/Roaming/SketchUp/SketchUp 2018/

Have you considered just downloading the 3Dconnexion drivers from the website and installing them correctly to see if that takes care of it?

I have uninstalled and reinstalled the 3DConnexion drivers a few times. Did not help.

In the meantime I have copied the entire SketchUp program from that other PC to this PC, using a tool called Total Uninstall Professional which can copy installed programs including all their settings and registy entries.

Now at least the SpaceNavigator is working again, and its Ruby file “3DxSketchUpExt.rbe” no longer appears in that error message when starting SketchUp.

However, these other four extensions still show the same problem:

  • Dynamic Components
  • Advanced Camera Tools
  • Sandbox Menus
  • Trimble Connect

I have uninstalled all of them several times from the extension manager in SketchUp, and deleted the folders belonging to them under C:/Users/[Username]/AppData/Roaming/SketchUp/SketchUp 2018/SketchUp/Plugins. I even reinstalled all of them directly from the Extension Warehouse.

However, when SketchUp starts up even when those 4 extensions had been uninstalled and their folders deleted, the folders are immediately recreated, the extensions installed and SketchUp then reports that it has no access to the folders. I can’t believe this. Also, these extensions keep reappearing in the Extension Manager, even though I uninstalled them in all perceivable ways.

Where do these extensions come from if I uninstall them and delete their associated folders?

Why wouldn’t you just download the installer from the SketchUp site and install it correctly. From what I’m reading, you are just creating work and trouble for yourself.

Installing the program correctly means right clicking on the installer and choosing Run as administrator from the context menu.

I did that a zillion times already and it didn’t help.

The problem could be related to this:

…but gotten even more severe.

These are the “Shipped Extensions”. They come with SketchUp.
They are installed from a “distribution” folder into your %AppData% “Plugins” folder the first time SketchUp runs and anytime SketchUp starts and detects that their “Plugins” subfolders are missing.

So if you delete their “Plugins” folders, and then restart SketchUp, it will recopy these 4 extensions into your user “Plugins” folder, then it will start the extension load cycle. Often though, these extensions will have a newer version in the extension warehouse, and you’ll need to update them after doing this kind of “manual reset”. (Note, that when you delete these extension subfolders, also be sure to delete the extension registrar .rb files with the same name from the “Plugins” folder.)

Now to the specific error. It looks like the file can be found by the load cycle. But there is an issue with reading the files. This might be caused by a unicode problem on your “problem machine.”

I would close all applications, and uninstall the C runtime that SU2018 uses, reboot and reinstall the latest version downloaded from Microsoft Downloads. Then reboot again, and restart SketchUp.

FTR, I have “Microsoft Visual C++ 2015 Redistributable” ver 14.27.29112.0 installed and everything is working fine with SketchUp 2016 through 2021.

Note: You did not say what Windows version you are running. This runtime may have been distributed with Win10.

Now that sounds like something.
I shall try this asap and report back.

OTOH, at the moment it’s running perfectly (with those 4 “Shipped Extensions” deactivated in the extension manager).

Therefore I might go for the “never touch a running system” approach for the time being. However at the latest should I have to install SketchUp 2018 the next time, I’ll make sure to come back and try this.

In my case it even is a newer version called Microsoft Visual C++ 2015-2019 Redistributable (x64) v.14.28.29325.

Strangely however, now my Windows Update wants to install this ancient stuff:

Security update for Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package (KB2538243)

I wonder why I would need this?

Probably for a older application.

And yes I also have the combo 2015-2019 runtime. (Was a type on my part) MS used to have a separate library for each Visual Studio release.) I wonder why Windows Update has not asked to update it ?

Do you have problems loading any other extensions ?

Do you have the latest update of SU2018 installed ?
