Could not find or load the Qt platform plugin

Expected behaviour

When starting owncloud.exe the application should start running.

Actual behaviour

The following error is thrown on start:

This application failed to start because it could not find or load the Qt platform plugin "windows" in "".
Available platform plugins are: minimal, windows.
Reinstalling the application may fix this problem.

Note that this error is not thrown (and the OC client runs as expected) when running owncloud as administrator.
Reinstalling or Uninstalling + Reinstall did not fix the problem. Also used a different location (D:\Programs instead of C:\Program Files).

Steps to reproduce

  1. Double click on "owncloud.exe"

Client configuration

Client version:

Operating system: Windows 10 Home 64bit

OS language: English

Qt version used by client package (Linux only, see also Settings dialog):

Client package (From ownCloud or distro) (Linux only):

Installation path of client: D:\Programs\owncloud\


Logs are not created as owncloud doesn't start (it does create a log file when running as administrator, but no problems there).

And does it work on C:/ ?
If no one else ever reported this then it is most likely a permission issue related to your local machine/drive?

Thanks for your reply. Unfortunately it didn't work in C:\ either and nothing changed on my machine yesterday (I shut the laptop down at work, came home, turned it on, got this message).

OK, here is an update. I remembered I installed another program called Blender (for 3D image/video creation), just removed this and now owncloud works again...

interesting. Did you do anything special for installing Blender? Is there anything odd in the setup there?

Interesting indeed... I did try finding a solution on Google and found this error message on a few other forums (not related to owncloud), however, the solutions mentioned there did not help me (copy a DLL file). Blender was downloaded directly from their website and installed using all default settings. I didn't notice anything special there.

Error still there. Windows 10, Blender from the webpage, ownCloud doesnt start until Blender is uninstalled.
