Torizon IDE Extension "Could not activate"

DaveM · March 16, 2026, 3:26pm

This has happened a few times to me, so figured I’d report.

The VSC extension updated (to pre-release 3.3.117). When restarting VSC, I get:

[03-16 08:18:47.314] Activating Torizon IDE ...

[03-16 08:18:47.315] Torizon IDE version :: 3.3.116

[03-16 08:18:49.245] ERROR :: Could not activate Torizon IDE extension :: TorizonCore Builder extension is not up to date. Please update the extension from VSCode Marketplace."

When looking at the TorizonCore Builder extension, it says “This extension is no longer available on the Extension Marketplace” and is sitting at 0.0.24 version. When I look at “Install a specific version”, I see 0.0.25 up there but when trying to install, I get “Error while installing "TorizoneCore Builder extension.

I guess I could uninstall the main Torizon IDE extension and see if things get better, but that seems quite destructive for this operation? Why isn’t it just pulling the “new” TorizonCore Builder version?

Hi, I’m the Toradex AI Assistant.

I might make mistakes or occasionally get you wrong. Our support team will step in if needed.

Based on the error message you’re encountering, this appears to be a dependency issue between the Torizon IDE Extension and the TorizonCore Builder extension in VS Code. The main extension is expecting a newer version of TorizonCore Builder but can’t find or install it.

Troubleshooting Steps

1. Check Extension Dependencies

The Torizon IDE Extension has dependencies on the TorizonCore Builder extension. When the main extension updates, it may require a compatible version of its dependencies.

2. Clean Extension Installation

Try this sequence to resolve the dependency conflict:

Uninstall both extensions completely:
- Uninstall “Torizon IDE Extension”
- Uninstall “TorizonCore Builder” extension
Restart VS Code completely
Reinstall from marketplace:
- Install the main “Torizon IDE Extension” first
- This should automatically pull in the correct version of TorizonCore Builder

3. Extension Marketplace Issues

The message “This extension is no longer available on the Extension Marketplace” suggests there may be a temporary marketplace issue or the extension ID has changed. This sometimes happens during extension updates or reorganization.

4. Alternative Installation Method

If the marketplace installation fails:

Check if you can download the extension files (.vsix) directly from the VS Code marketplace website
Install manually using the “Install from VSIX” option in VS Code

5. Version Compatibility

The error indicates version 3.3.116 is running but 3.3.117 was expected. This suggests the extension didn’t update completely or there’s a caching issue.

Prevention

To avoid this in the future, consider:

Avoiding pre-release versions if stability is important for your workflow
Waiting for stable releases of the extension updates

The uninstall/reinstall approach, while seeming destructive, is actually the most reliable way to resolve extension dependency conflicts in VS Code and shouldn’t affect your project files or configurations.

Hey @DaveM,

Are you able to post the full logs for when you try and update the TorizonCore Builder extension? You should be able to update this to 0.0.25. Which most likely will be the solution to initial error.

DaveM · March 17, 2026, 7:49pm

Hey @eric.tx …happy to. Which log files would you like to see?

eric.tx · March 17, 2026, 7:54pm

Hey @DaveM

When you try and update the Torizon-Core builder extension to 0.0.25 and you get “Error while installing "TorizoneCore Builder extension.” Where is this error showing? or is there more information to this?

When starting up, the “OUTPUT” window shows:

[03-17 12:55:34.134] Activating Torizon IDE ...

[03-17 12:55:34.135] Torizon IDE version :: 3.3.118

[03-17 12:55:35.917] ERROR :: Could not activate Torizon IDE extension :: TorizonCore Builder extension is not up to date. Please update the extension from VSCode Marketplace.

And a notification pops up in the bottom corner with a red X that says “Could not activate Torizon IDE extension :: TorizonCore Builder extension is not up to date. Please update the extension from VSCode Marketplace.”

When clicking inside the Extensions area and navigating to the “Extension: TorizonCore Builder”, there is a yellow triangle with explanation mark in it that says “ This extension is no longer available on the Extension Marketplace.”

When I click in the second dropdown that initially says “Uninstall”, there is an option for “Install specific version”. I click that, it shows

And I click 0.0.25. I get another red circle notification that says “Error while installing ‘TorizonCore Builder extension”. Nothing else happens in the OUTPUT window.

btw, inside of the .log directory, there is a file “updater.txt” that has recent contents of:

sudo: /opt/updater/updater.xsh: command not found

@eric.tx Any other tips?

Hi @DaveM

You don’t state above which OS you are running on but I’ll assume it’s Windows as there are some peculiarities with that setup that may be the root cause of what you are seeing. When installing the Torizon IDE extension in Windows, there is a setup wizard which will install WSL and take care of several dependencies. Then it uses the WSL extension to connect to your WSL instance and inside there the Torizon IDE and TorizonCore Builder extensions will be installed. The TorizonCore Builder extension is not available directly on Windows and I am guessing that is what you are seeing here. More details of this setup process are here.

I don’t have a theory as to why you only recently started seeing this but I suggest as a first step, completely remove and reinstall the Torizon IDE and WSL configurations. You can do this from VSCode, but not when connected to WSL so make sure to close that remote connection so you are pointing at the Windows Instance. In the command window (Ctrl-Shift-P I believe) you can look for “Torizon Uninstall” and you should see a command to “Uninstall and Clean Torizon for WSL”. Then restart everything and follow the instructions as shown in the link above. Hopefully that will cleanup whatever weirdness your system was in.

Thanks @drew.tx … I just went ahead and did the extension uninstall, vsc close, vsc open, install. And I actually left it on the standard version instead of pre-release just for safety’s sake. It did pull in 0.0.25 tcb during the 3.3.0 install, so all is well again. And yes, it’s windows and started doing this maybe 6 months ago or so. I would assume it’s tied to when the tcb extension version changes, as that one doesn’t update as frequently as the pre-release of the IDE extension.

drew.tx · March 23, 2026, 3:44pm

Interesting. I normally use Linux so I have not seen this behavior but I know the IDE developer team uses Windows quite heavily. Hopefully this was just some quirk of your install and not the symptom of a larger behavior but please do let us know if it recurs. For now I guess we call this one solved.

DaveM · March 23, 2026, 8:13pm

Ya, if y’all and other users don’t see this behavior, I’m assuming it’s my environment only (unless everyone else just uninstalls/reinstalls frequently). I guess it’s “solved” as in the uninstall/reinstall cleaned it up for now.

Hi @drew.tx and @DaveM

I’ve just seen this behavior (or a behavior really similar to this one).

I installed my new Win 11 PC one month ago, and I setup a fresh Torizon IDE Extension following setup process here.

Everyhting worked fine until some days ago, but suddenly I have the error.

[03-24 11:43:21.358] Activating Torizon IDE ...
[03-24 11:43:21.358] Torizon IDE version :: 3.3.0
[03-24 11:43:21.709] ERROR :: Could not activate Torizon IDE extension :: TorizonCore Builder extension is not up to date. Please update the extension from VSCode Marketplace.

Based on @DaveM output, I see Torizon IDE version as 3.3.0 (not 3.3.118) and I think this is because I’m NOT on the pre-release.

I can’t update inside WSL-Torizon

For tcb extension, I’m on 0.0.24

but I could manually update

@drew.tx Do you want me to do some test?

Or should I manually update and see what happens?

drew.tx · March 24, 2026, 1:28pm

Hi @vix

Can you confirm that you installed using the Windows Installation Wizard? Or did you do the manual setup?

vix · March 24, 2026, 2:18pm

Yes, I installed using the Windows Installation Wizard on my fresh Windows 11 PC.

And the installation completed smoothly without any issue.

DaveM · March 24, 2026, 2:20pm

Cool…well, not cool for you @vix , but I’m glad I’m not alone on the island. When I tried to update TCB to 0.0.25, it errored out.

drew.tx · March 24, 2026, 2:40pm

It sounds like you may just have not had the “automatic update” tickbox checked. If the one inside WSL is out of date and not auto-updating, the version of the extension in the Windows instance will not activate. In that case you may need to manually connect to WSL and update the extension.

vix · March 24, 2026, 2:45pm

I confirm that this is not checked.

This is my default setting for VS code extensions, because I would like seeing “updates available” and then deciding if update or not.

But, with the checkbox diables I don’t see any update available neither for Torizon IDe Extension, nor for TorizonCore Builder.

@drew.tx do you want me enabling that checkbox and see what happnes?

drew.tx · March 24, 2026, 2:48pm

Yes please try that. Both inside WSL and in the Windows host itself.

vix · March 24, 2026, 2:56pm

I did it, but the extensions in WSL-Torizon are not updated.

Should I manually install the latest release for Torizoncore Builder?
