Hi,

You can run App Manager in the already opened console window by doing the following. Right-click on the launcher icon, then click “Properties”. In the “Verge3D for Blender Properties” dialog go to the “Shortcut” tab, then select and copy the content of the “Target”.

Open the command prompt (start menu, then type “cmd”, then select Command Prompt from the list). Paste the copied “Target” content in the opened command prompt, then press Enter.

Once the error happens, please copy the entire content of the command prompt and send back to us.

Hope this is not too much trouble!

Thank you for the log, it really helped!

Is it possible that the “v3d.js” engine module got edited somehow? It appears that some invalid characters (with different encoding) were inserted into it. We’re going to dive deeper into this issue. In the meantime you can copy the file from C:\Program Files\Verge3D_for_Blender\build\v3d.js to your application folder(s).

Hi Alexander,

First, your help is greatly appreciated, thank you!

I did not edit the file, only thing I do after installing is try opening the application. Do i need to copy the v3D.js from C:\Program Files\Verge3D_for_Blender\build\v3d.js to my verge project’s folder? what will that accomplish?

That’s really strange, maybe it’s some disk issue or something like that.

Anyway, copying that file from Program Files should reset the engine runtime in the corresponding app to its original (unlicensed) state. Afterwards you just need to activate your installation by entering your license key anew.
