Blender 4.4.0 - Substance add-on 2.2.0 - Can't Install Integration Tools

Hi @Ymmanuel_F ,

It still doesn't work on my side. To resume, I work on a Mac with Blender 4.5.3. I've downloaded the Mac zip file. I has not been automatically uncompressed by the system, so the name is the original one (Substance3DIntegrationTools-2.3.0-Darwin.zip). After having dragged and dropped it inside Blender, the warning message pops up: "Report: Error. Error in manifest Archive has no manifest: "blender manifest.tomt".
Thanks for you help.

I had the same issue, Windows 11 doesn't come with the component installed. What worked for me was installing WMIC through Windows' optional features.

Once installed, the add-on worked normally.

Hi Jessica just to clarify, the toolkit_version_empty_error is a pretty different error and is well identified,

this can happen if the zip file is not recognized as the official Integration Tools downloaded from the website,( renaming the zip file can cause this issue as well)

And because of that the version of the installed toolkit is found

What is the name of the Zip file you downloaded or you are trying to use to install the integration tools

Cheers

I'm actually having the same issue that Gwendal_78 mentioned. I'm on a Mac, M4, Sequoia 15.5, and running Blender 4.5.1 LTS. When attempting to install the zipped plugin files, the base plugin installs just fine, but the integration tools returns an error: Substance 3D in Blender: [Code_Response.toolkit_version_empty_error] Error while installing the Substance 3D Integration Tools. I've attached an image.

Hi Im the developer of the addon, the compatible version for Blender 4.4 has been out and in use by many users since April 29th, this issue was because of a change in the blender api, and should fix the original post issue:

Error: Python: RuntimeError: could not create instance of SUBSTANCE_OT_install_tools to call callback function 'invoke'


there was also the WMIC issue, that will be solved in the next update (this only affects windows) and Bret mentioned how to fix it

For the commmont from Gwendal78, i would need more context since there is no info of their issue

Sorry, but it's still the same problem! I'm on MacOS 15.5 (24F74) with Blender 4.5. Could you verify on your side before give us an answer? Thanks a lot.

Hi, 

The release went out on April 29th.
You can access the latest builds here: https://www.adobe.com/products/substance3d/plugins/substance-in-blender.html

It's the end of July and we still don't have an update… What's going on?

@jonathan_5546 Apparently windows 11 no longer installs WMIC as default and it has to me installed manually.
This is done by going to Settings - System - Optional features
Selected "view features" then select " Add Option feature"
This will bring up a new window, scroll down the list to find WMIC, tick the checkbox, then press next, in the next window press Add.
You should now to be taken to a new window which shows the progress of the WMIC install under recent actions.
Note this will take a while to download, it not frozen, it took about 15 - 20 mins for me.
After this reset your computer and should be fine, when you click on the load in the substance tab, the file browser window should now display.
Hope this helps

Hi,
for me the Plugin Still doesnt work, i use blender 4.4.3, Substance Add-On and Integration tool is version 2.3.0.
The Installation works, but Loading a Substance results in the Error: WMIC Process is not installed. 

System is Windows 11.

Best Regards
