    I have put the qwindows.dll + others in the /platforms directory of the application.

    The application runs fine on several fresh installs of Windows (32bit and 64bit). But for some people they get this error popup when trying to run the application.

    Any ideas?

    Here is the image popup: http://imgur.com/a/0PSfP

      Hi and welcome to devnet,

      Did you follow Qt's deployment guide ?

      Use windeployqt to prepare the deployment ?

      On a side note, this question has been asked many times already, please use the forum search feature.
