Hi,

I built a DLL that includes a win32 window that invokes a QT dialog. I created the folders structur with all the DLL needed as it was suggested from windeployqt.exe (including sub directory platforms with qwindows.dll). All is done on a windows 7 64 bits. I can run it on multiple machines with no problem but I have other machine that when I run it , I am getting the error message:"This application failed to start because it could not find or load the qt platform plugin windows". All the machines I tested are windows 7 64 bits and none of them have the QT installed. I am struggling with this issue for a while and it is important to me to understand why this is happening. Can anybody suggest me how to handle this problem and what tools can i use to figure it out?

Thank you.
