Cannot launch Calibre on PC



  • I have 2 PCs and on one of those I have installed PyQt5 development environment, and on this platform I cannot launch the calibre, a library application that was developed with QT, with this error 5769d62d-829c-42c8-9d3d-4bc61a266971-image.png

    While on the other PC it works perfectly. Does any one have idea how this is happening and how to solve the problem?

    Your computer's PATH probably contains a folder that contains a version of Qt DLLs that are incompatible with Calibre. You must find the folder and remove it from your PATH.
