The source code compilation for all versions

[Pradeep Kumar]

We have windows 7,8 and 10. we have compiled Qt code in Win 7, able to load ewo in WinCC OA without any problem,
but in Win 10 the same code , when we compile and provide the ewo for WinCC OA,

we are getting error has EWO could not be loaded.
The EWO "C:\\Siemens\\Automation\\WinCC_OA\\3.15\\bin\\widgets/windows-64/TestingWin10.ewo" is version "1", but we can only load version "4"

Any specific reason are we missing anything?

Typically this error message appears if the EWO cannot be loaded correctly. Eventually your EWO uses a dependency which does not exist in Windows 10. Normally a seperate compile for Windows 10 is not necessary.

With dependency walker you can check which dependencies the EWO has and which cannot be found.
