Unable to Start Sweet Home 3D After Installing Pan 3D View + Wiring 4.4 Beta 2
Subject: Unable to Start Sweet Home 3D After Installing Pan 3D View + Wiring 4.4 Beta 2

Hello everyone,

I recently tried to extend Sweet Home 3D (Windows 11 Pro, 64-bit) with the Wiring 4.4 Beta 2 plug-in. Since the author mentioned that it requires Pan 3D View > 3.0, I first installed Pan 3D View 3.3. The application confirmed that the plug-in would be available on the next restart.

Encouraged, I immediately installed Wiring 4.4 Beta 2 as well, which gave me the same confirmation. However, after restarting Sweet Home 3D, the program would no longer start. Instead, I now only receive the message asking me to install Pan 3D View – even though it is already installed.

At the moment I am unable to open Sweet Home 3D at all.
My questions are:

How can I recover Sweet Home 3D so it will start again?

Is there a safe way to remove the Wiring 4.4 plug-in without having to reinstall everything?

If necessary, how can I disable Pan 3D View as well? I would rather work without these extensions than risk losing access to the software.

I would be very grateful for any advice or clear steps to solve this issue.
Also, if this is a common problem, perhaps it could be highlighted in the forum so other users don’t run into the same difficulty.

Many thanks in advance for your support!

Best regards,
T_R

Re: Unable to Start Sweet Home 3D After Installing Pan 3D View + Wiring 4.4 Beta 2
You can remove a plugin by simply removing the .sh3p file from the 'plugins' directory that is located under the Sweet Home 3D directory. This is a hidden directory so you will have to switch its visibility in your filemanager.
On the FAQ page you can find where that directory is, search for "files and folders separated from the program".

Start with only removing the Wirings plugin and see if you can start Sweet Home 3D now. If you can start without the Wirings plugin then try an older version of that plugin. It is possible that the latest version doesn't work with your Sweet Home 3D 6.2 version.

Try the latest 7.5 version of Sweet Home 3D. I doubt that is slower than your 6.2 version and you have less chance of running into compatibility problems in the long run. You can make a backup of the previously mentioned directory to restore it if a new install cleans up that directory.

Re: Unable to Start Sweet Home 3D After Installing Pan 3D View + Wiring 4.4 Beta 2
Hello Kiet,

thank you again for your help and the detailed explanation. I checked the path on my Windows 11 system, and the plugin directory is located at:

C:\Users[Username]\Sweet Home 3D\plugins

I can see my installed plugins there, but unfortunately none of the ones I wanted to remove (Wiring 4.4 Beta 2 or Pan 3D View) are actually in that folder. That makes me wonder if there might be another location where Sweet Home 3D keeps them.

For now, I’ve created a backup of the entire folder, just in case. But since I couldn’t find the mentioned plugins, I am still stuck and unable to restart Sweet Home 3D.

Would you have any idea where else these plugins might be stored, or how I could completely remove them from the installation? Any further guidance would be greatly appreciated.

Thanks again for your patience and support – it really helps a lot!

Best regards BTW : my Footer about Laptop is outdatet. I run win11pro 64 bit, IBM Thinkpad 490, in Germany( unfourtunatly) will update soon

Re: Unable to Start Sweet Home 3D After Installing Pan 3D View + Wiring 4.4 Beta 2
@ Keet,
(sorry typo before)
thank you once again for your guidance – it really helps to have such clear instructions.
I discovered another directory on my system:

C:\Users[User]\Application Data\eTeks\Sweet Home 3D\plugins

In that folder I finally found the Wiring 4.4 file and removed it. Interestingly, none of these folders were hidden on my Windows 11 system, so maybe that detail could be updated for other users too.

Unfortunately, after removing the file, Sweet Home 3D still shows the same message asking me to install the required plugin, and it refuses to start. So I’m still stuck at this point.

Would you have any further ideas what I could try next? I would be very grateful for any additional help. Your support is really appreciated – without it I would be completely lost.

Best regards,

Re: Unable to Start Sweet Home 3D After Installing Pan 3D View + Wiring 4.4 Beta 2
I don't know anything about Windows but that you found two different directories with plugins seems wrong. It could happen that Pan3DView is installed in one and the Wirings in the other. Then the Wirings plugin will not find the Pan3DView plugin.

Copy both plugins in only one of the directories. If that works OK, if not then move them both to the other directory. If that works you have found the directory that is the correct one for your current Sweet Home 3D. Now it should work.

ETA: Once you can start Sweet Home 3D you can easily find the correct directory: Menu > Help > About. Click the button "Libraries".
This will display a dialog with three lists. The bottom list shows the installed plugins. If you click one it should take you to the directory where it is installed. It is one of the two directories you found with plugins.

Re: Unable to Start Sweet Home 3D After Installing Pan 3D View + Wiring 4.4 Beta 2
Hello Keet,

thank you once again for your patience and guidance. I realize I might be reaching the limits of Microsoft-related knowledge here, and I hope that some other experienced forum members might be able to chime in with advice and practical tips.

I’m especially concerned about the alternative: even if I uninstall and reinstall everything, how can I safely preserve all my add-ons and libraries? There is a huge amount of data, and I would like to avoid having to reinstall or download everything from scratch. Copying everything back blindly might also reintroduce errors if some system references or paths are involved, since the error message must be coming from somewhere.

Any additional help, suggestions, or insights would be deeply appreciated. Thanks so much again for your time and support – it really means a lot!

Best regard

I like your signature smile

So, don't give up!
As Keet I'm also not a Windows fan but I know some basic things about how the computers works.
My suggestion:
1. To preserve the current installation with all add-ons:
Rename the eTeks folder to eTeksBak(or whatever)
2. Install the official version 7.5 from this site(not from MS store)
3. Test it WITHOUT any furniture, texture or plugins.(try 32 or 64bit)
4. Go to your eTeksBak\Sweet Home 3D folder and copy the furniture and texture folders to your new installation
5. For the plugins you will have to test it one-by-one to see which one break your program and delete it.
That's what my unique neuron could produce crying

Re: Unable to Start Sweet Home 3D After Installing Pan 3D View + Wiring 4.4 Beta 2
Creating a backup of everything you have now is easy but it possibly requires a lot of disk space. Backup to an external drive with enough diskspace.

What you must backup:

1 - The Sweet Home 3D directory you just found. Backup the complete Sweet Home 3D directory but the
minimum you should backup is:
- the Preferences.xml file
- the directories "plugins", "libraries", "textures", and "languages"
- all the .pref files (you can zip them to one file)
- if they exist: the pan3dview.xml file and the "PluginManager" directory
The "work" and "recovery" directories should be empty if Sweet Home 3D is not running. They will be created when Sweet Home 3D is (re-)installed.

2 - Your projects and downloaded models. These should be safe when you install a new Sweet Home 3D but of course they are lost when you reinstall Windows. It is wise to make regular backups of these anyway. Or at least add the new and changed files to your existing backup.

After a new install of Windows you first install Sweet Home 3D.
Then you go to the newly created Sweet Home 3D directory and restore backup 1 to it.
Then you create a new directory for your projects and downloads and restore backup 2 to that directory.
You should create the new projects/download directories with the same name and location as you have them now. That way you will not have any path issues.

If you only install a new version of Sweet Home 3D (7.5) then follow what dorin wrote.

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.

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

If I'm not mistaking then Emmanuel Puybaret implemented a check in version 7.5(?) so that plugins that fail to load don't block starting Sweet Home 3D.

Recommendation:

This is not specific to the Pan3DView plugin, it can happen with any plugin and has happened in the past.

Thank you, I'm glad your problem is solved!

That's strange! It should never happen.
Try to make an completely fresh install as I've described and take a look into Sweet Home 3D folder after you run the program at least once.
It should make all folders with lower case(e.g. plugins NOT Plugins).
With some upper case could be the PluginManager folder if you've installed PluginManager-1.5.3.sh3p under plugins.

Re: Unable to Start Sweet Home 3D After Installing Pan 3D View + Wiring 4.4 Beta 2
That's strange indeed. Personally, I'm also using Windows 11 Pro, and absolutely all my plugins are in the following directory:
C:\Users\(myname)\AppData\Roaming\eTeks\Sweet Home 3D\plugins
As for Pan3DView, it can indeed crash the software. This happened to me with my old I5, and I had to remove it from my plugins. On my latest I9, I haven't dared to reinstall it yet!

Re: Unable to Start Sweet Home 3D After Installing Pan 3D View + Wiring 4.4 Beta 2
Sad to hear this. I am the developer of these plugins and I have found no problem using them (I'm using SH3D 7.5 on Windows 11 as well).

First, I recommend to use the Plugin Manager to install plugins, it will always provide the latest version which is compatible with your installation (not just SH3D version, but also Java version).

Second, if you want to give a try, install the plugins again (once at a time): if it still fails, start the program from the command line, copy the output and post it here, maybe I will understand what's going wrong with your installation and I can provide a fix.
