Re: Unable to Start Sweet Home 3D After Installing Pan 3D View + Wiring 4.4 Beta 2
Workaround for SweetHome 3D (SH3D) Plugin Issues on Windows 11 (Zulu Platform / Java-based)

I recently encountered a recurring issue while attempting to install and run plugins in SweetHome 3D 7.5 on Windows 11 Pro, using the Zulu Java Platform (x86 architecture). The problem arose during plugin installation and prevented the software from starting. Here is a detailed account and a constructive workaround.

Scenario:

I attempted to install the PAN 3D View plugin, a prerequisite for other plugins such as Wiring.

After installing PAN 3D View, I attempted to install the Wiring plugin.

Upon restarting SweetHome 3D, the splash screen briefly appeared, followed immediately by a popup instructing me to install PAN 3D View, even though it had already been installed.

The software could not start, creating a circular dependency: it could not verify the prerequisite plugin because the application itself did not launch.

After two failed attempts, SweetHome 3D would no longer start at all.

Workaround / Solution:

Following advice from Keet, I investigated the plugin folders. The path indicated in the official FAQs is inaccurate for Windows 11.

I located the active plugin folder here:
C:\Users\User\Application Data\eTeks\SweetHome 3D\Plugins

The PAN 3D View plugin could not be removed initially because it was in use. Windows reported:

“The file is open in Zulu Platform x86 Architecture.”
This indicated that the file was locked by a running Java process.

I opened Task Manager, identified the Java process associated with Zulu Platform / SweetHome 3D, and terminated it.

Once the Java process was stopped, I was able to delete the PAN 3D View plugin from the folder.

I then restarted SweetHome 3D. The software launched successfully.

Additional Observations:

There exists a second, nearly identical plugin folder under:
C:\Users\User\eTeks\SweetHome 3D\Plugins
containing many, but not all, plugins. This duplication is confusing and complicates troubleshooting.

Constructive Suggestions:

For Users: If a plugin cannot be removed due to being “in use,” check the Task Manager for active Java/Zulu processes and terminate them before retrying deletion.

For Developers: Consider:

Using a single, centralised plugin directory to reduce confusion and prevent circular dependencies.

Updating installation paths and FAQs to reflect Windows 11 specifics.

Implementing checks that prevent startup failures due to plugin dependencies, ensuring that the application can always launch even if a plugin is temporarily missing.

Recommendation:
I strongly recommend avoiding the use of PAN 3D View on SweetHome 3D 7.5 with Windows 11, as it can prevent the software from starting and complicate plugin management.

Acknowledgements:
Special thanks to Keet, whose guidance was instrumental in identifying and resolving the plugin issue.
