[solved] Cannot uninstall Qt 5.4 on Windows 8.1

  • Hi,
    I recently ran the Qt Maintenance Tool, which told me my installation was corrupt and I should reinstall it. (I only installed Qt a week ago and have hardly touched it!)

    When I tried to "Remove all components" I got an error message telling me, "ProductName should be set".

    I don't know what to do. Can I remove Qt manually?

    Thanks, I would appreciate any help.

  • I managed to uninstall Qt 5.4 after reading this post:

    In my Qt folder, there was a file,, which I renamed to maintenanceTool.dat.

    I then ran the maintenance tool again and this time, it successfully uninstalled Qt.
